The pores are sized on a molecular scale, especially if your alloy is well and truly mixed. You may need to an electron microscope to compare the pre-HNO3 treated electrum and post-HNO3 treated gold. I would hazard a guess that the gold powder from precipitating the chloroauric acid and the silver powder cemented out of the silver nitrate solution are on a molecular scale for particle size. Further, I speculate that the gold powder could be compressed into chunks similar to when other metals are sintered into shapes because of gold's "self-welding" property. They would make amazing paint pigments although expensive. Have you ever allowed the chloroauric acid to evaporate making pure gold crystals? The white precipitate could be lead sulfate or silver chloride or nitrate. You use a shot of H2SO4 to precipitate the lead; some silver could also be carried over and rendered into an insoluble salt.
I'm an oil painter, and I once ground 23.5k gold leaf into linseed oil and made a gold paint, a sort of crude shell gold, which is what the old masters used for their icon paintings. Truly though, when it gets broken up, it really loses its shine, and when you paint it on, it's really hard to shine it back up unless the paint is very dense in gold content. I plan to experiment more in the future, but I'm thinking it's probably better to just lay down some gold leaf for the vast majority of situations in which a golden look is required. Also, if you're actually looking to paint something that looks like it's made of gold, it's paradoxically better to simulate this with a variety of pigments like blue ridge yellow ochre (which looks kind of like the inquarted gold, though there's no gold in it), as well as cadmium yellows/oranges, and my favorite, naples yellow.
I just so happen to have within arms reach a couple of dry troy ounces of double refined (SMB & Oxalic Acid) gold in a small beaker and my USB microscope. I can see small holes throughout the pieces. Nothing I would call a honey comb structure but holes nonetheless. Perhaps a stronger microscope would reveal a more defined structure. Cool stuff Sreetips...
As others have already commented, the honeycomb structure is probably too small to see. Crystal size can be increased by rate of cooling when solidifying the inquarted gold, since your inquarted gold is poured as shot into water the solidification is almost instantaneous and hence the crystal structure is very small. I would hazard a guess that a very slow cooling rate of the inquarted gold would yield much larger pores. If that were the case, the larger pore size could also make the silver extraction more efficient 🙂
Awesome video. Thank you for more insight on the process. I’m waiting on a colorful metaphor to slip in, but I get the desire to have a PG video for professionalism.
Hey Mr. Streetips. Something you could maybe expand on or talk about in future videos: Could discuss what are considered base metals that you get out after inquartation. Also I always think of this while watching you pour off rinses, that the gold is much heavier than regular dirt and the like, and you can use that to your advantage, whether it's panning for gold, shaking it on a table, or in your case rinsing/pouring it without losing any gold powder. Also I dont know if you have ever talked about this, but if copper is more reactive than silver, thus being able to cement silver from solution, could you also cement gold out of solution onto pure silver? Maybe that would be a neat experiment if so, even if smb makes a whole lot more sense. Still watchin your channel after years now, and its always interesting
I’ve been watching your videos for as long as I can remember and like you said seeing that beautiful gold bar never ceases to amaze me. Keep up the great work!
Oh little tip for those microscopes Sreetips (use them allot to tell the gender of tarantulas and other bugs here). I found the light that comes from the ring a little harsh even when turned down. If you turn lights off and get a desk lamp with a "cool white bulb" (they appear pure white almost blue) the image you get and details on what you are observing are vastly improved. Another thing i sometimes use if the object i am looking at is shiny (in your case might be often!) is some polarizing film. Just cut a little bit out and stick under scope. This will remove any glare :) You can also just get some polarized sun glasses and stick the lens under but it might distort image due to curve in lens.
Thanks for the awesome video!! But I have to know, when you pour off your way solution rinsewater how much gold is running off? Maybe next time, dump your Waste solution into a clean beaker let it settle, draw off liquid, melt to button and weigh? I know you eventually get it when you process the waste solution, just curious. Thanks again watch all your videos very much appreciated.
That silver cement process is incredibly fascinating. These chemical processes you do with precious metals helps me to better understand the chemistry of geological formations of metals in their various states. Like how gold is made in the earth and then gets deposited in different places. In ore, nuggets etc.
@@enkidu9705 , God made the gold. I'm talking about the geological data that talks about gold coming from deep within the earth in lava and or geothermal fluids that deposit gold in rocks or in nuggets near the surface. I never understood that gold could be in solution until I saw. Sreetips do it . Then it mad sense to me how gold could be in different forms .
I'm so confused; any thoughts: If the inquartation gold is poured into plates or just placed into filter baskets and copper plates or filter baskets were alternated. Then if the series connection of plates or baskets between the different potential plates or baskets suspended in electrolyte would create an energy producing battery. Between the anodes and cathodes the silver will move from the gold through the electrolyte and attach to the copper plates. The completed reaction purifies the gold while producing energy as electricity as opposed to it as heat. I wonder how much potential electrical energy each cell of a silver gold - copper battery compares to a lithium iron phosphate 3.5 volts per cell. And I wonder what if nitric electrolyte were substituted with dry electrolyte? I really like thinking about the silver cell too. Mostly I wonder about how the power supply can only control the voltage. In this silver cell system the current flow is limited to the resistance. Apparently, a relatively low voltage is desirable and the amperage becomes a product of the resistance of the electrolyte. What would result from maintaining the low voltage but increasing the current amperage? Would the crystal size differ? Would the speed and deposition rate change? How would placing a resistance load into the circuit on either the anode or cathode pos/neg wiring control the current amperage? Would the increase in the circuit amperage best be controlled by multiple LED's or resistors twisted together in parallel or would a variable potentiometer like a radio volume pot be better? Since increasing the electrolytic silver cell amperage while maintaining the low voltage provides more control of the production I wonder what effect occurs when decreasing the cell voltage to 1.5 volts while increasing the circuit amperage / load to 5 amperes produces? ✌️♥️👍
Lovely video as always. Are there any tips for getting started on the melting process of precious metals, such as what gas to use, flux, best types of crucibles, and insuring there isn’t impure substances?
I think it's notable that the inquarted gold has formed these little nugget like clumps that look nearly identical to some natural nuggets. I wonder why . As for seeing the honeycomb structure, you probably just need a more powerful microscope . I'm very curious to see a drop of the gold in solution on a slide under a very powerful microscope. 🤔 Cool video, man . Thank you 👍
you need to place it between two pieces of glass so it is flat, the 3d structure otherwise causes the camera in the microscope to fall out of focus.....
I always wondered if agitation while precipitating the gold out would form less small particles and hence less temporary"loss" in the waste bucket. Even if you will recover it later on it might make the cleaning of the precipitate easier?! Do you think it's worth a try?
My guess on the mystery chunk is a gemstone. As to what it may have been, your guess is probably better than mine. As for what that reddish discoloration after 2nd AR refining, I wonder if there may have been enough free acid in the solution to start pulling gold back....?
May have been an opal. The red - that was just baffling. Stuff like that never happens. Only when I’m shooting video. Like the refining gods are frowning.
If your ring were a lower karat it would have been something more like reduction guilding which is where you allowed to work for a short period of time as a surface treatment to give it the appearance of 24 karat. Have you ever done anything like that? It might be something to bring your experience to bear on and perfect the details through your vast knowledge so we can all get another little piece of the puzzle to add to our understanding of all things golden that would also be very interesting to see at the microscopic level
Do you have a formula or price list that you use to help you in determining how much to pay for karat gold from garage sales and other places you find items? I would image it has something to do with the karat and weight of the item. Also, do you happen to know your total expense amount for a processed gram of gold? Thank you!
I’ve tried extractions from soil, tailings. They are time consuming, produce little to no yield. And create lots of waste that must be treated prior to disposal. Unfortunately, it’s just not worth the time and effort.
It did have the appearance of a porous surface, but the holes are way too small to see with that or maybe any optical microscope. It was still worth the try. great video as always.
Carson makes a nice 100x-250x handheld microscope for around ten to twenty dollars that could do a way better job at showing the finer details. It also comes with a slide for the smaller stuff.
I would love to see you do an experiment on your rinsing, particularly how much gold you lose during your normal "rinse cycle" when you rinse off the pure gold. My thought is if you lose a tenth of a gram per rinse, 10 rinses equal a gram of gold. You could take some triple refined gold you know has no contamination, or at least a negligible amount, weigh it to the hundredth of a gram, refine two more times, melt into a bar and reweigh. Take note of how many rinses and what might be in the filter. It would give you an idea of how much you lose per refining so you can know how much to adjust your yield, how long before you need to clean container, etc.
I believe you more or less have your answer in this video here: czcams.com/video/RXkP-6QsL5s/video.html In that video Sreetips recover the solid gold particles at the bottom of five containers with rinsing solution, or gold refining waste. The solution gets poured into the stock pot and the solid particles gets recovered with aqua regia and SMB. The result is 16 grams of gold from the five containers, which I assume is more or less the result of five previous refinings. If my assumptions are correct, it would mean that Sreetips has lost 3.2 grams of gold per refining. It would be slightly more if we include what gets poured into the stock pot. In the video above (Inquarted Gold Under The Microscope) Sreetips expected a yield of 119.1 grams and got 116.7 grams, which means a loss of 2.4 grams. I think we can safely assume that most of the gold that is expected from each refining but never reaches the final yield, actually ends up in the refining waste, which is later recovered. With that said, I would love to see a video like the one i linked to above (Gold Recovery from the Waste Containers) again, with the added bonus of including the numbers from what Sreetips was expecting from the refinings compared with the actual yields.
@@HenricLassesson issue is there are too many assumptions of the issue which without actually counting and knowing how much you start with. Remember the scientific method. We have the hypothesis. We need to control as many variables as possible. I'm an avid watcher and know that Sreetips doesn't film all of his refinings. Besides, don't you want more content?
@@beauhodges7957 Of course; I would love more content. That's why I suggested the type of content I would like to see more of. I also know of the scientific method(s). I believe that your setup of an experiment could be quite beneficial. We can learn a lot from that. I do, however, see a few problems: 1) Refining gold that is already triple refined would be a waste of time and chemicals for Sreetips when he could be focusing on refining other stuff that will actually result in some extra money. My suggestion would be a part of his everyday refining anyway. 2) We don't know if the rinsing of the triple refined stuff will result in the same amount of lost gold as rinsing of inquarted gold jewelry. Less pure gold could very well result in more nano and mikro particles that will rinse off with the water, i.e. greater loss. 3) In order to account for variability, it would be best if the experiment would be tested at least three times (more if there is large variability). This comes back to my first point. Wasting time and chemicals once is one thing, but doing it three times would be even more wasteful. If the experiment, instead, is performed as a part of what Sreetips does anyway (refinings that are off camera) then it will not be a problem to account for variability. The video I linked to had five containers and it would not surprise me if Sreetips has some other results in his notes somewhere.
@@HenricLassesson true. My point with the triple refined gold was to remove contamination from the equation to limit that variable from the overall question. Start with a known amount, count rinses, dry product, cast into bar and reweigh. It would give a great idea how much is lost during the rinsing process with pure gold. I think we are not on the same page. My assumption on your comments is you are considering the total process, and all of the gold combined. Those videos where he cleaned out his "savings account" in the bottom of those containers we was fun to watch. (I always watch the day he releases.) In that case you are absolutely correct that there is enough in prior videos to make several assumptions about how much is lost. What I am considering is single refinings. You make excellent points, which would only improve the result. My thought process is to determine for each individual refining, how much is lost to rinsing? Then you can make certain assumptions about each subsequent refining you do how much you lose for each additional refining after the first. My thought process is to gather data to suggest that if you know you will lose a specific amount of gold in each refining, is the 2nd, 3rd, etc. actually worth the chemicals to refine? Hypothetically, if you lose 1 gram per refining to the stock pot, is that worth the additional chemicals to do a second refining. Or a third. If you lose .5 gram, that is $28 usd as of right now. I think no matter which way it is considered, I do want to see more stock pot videos. Super interesting.
@@beauhodges7957 No, I think I do understand what you mean. We are both talking about the rinse liquid being poured off at 21:23 right? We both want to know how much gold is being poured off at that moment. By the way, it’s not lost forever just stored for a later occasion. By using gold that is already triple refined, as you suggested, it will give us a precise amount of what is poured off from that very pure sample. But the question is if it will give us the answer to how much that gets poured off from a less pure sample, which is what we actually want to know. Or that is at least what I would like to know. I don’t know if the amount being poured off is affected by the purity of the gold or not. It could be. It will be affected by the amount of tiny particles suspended in the liquid. You have noticed the brown color in the first few rinses right? That is due to the amount of really small particles that didn’t have time to sink to the bottom. The size of the particles could be affected by several things, where trace amounts of other metals (when SMB is added) could be one factor. The concentration and temperature of the gold solution (when SMB is added) could be other factors that affect the particle size. The loss during rinsing would also be affected by the total amount of gold that is being rinsed and by the speed of the rinse (is Sreerips in a hurry?). In other words, there are many factors influencing the result, which makes it almost random. This is why I’m voting for testing this several times (under “normal” conditions) and taking an average of many trials instead of testing it very precisely once.
Also.... These last several chunky bars you have made have been quite spectacular. Any thoughts on doing some silver bars? Maybe with a bit of silver crystal from your electrolytic cell? ..... Maybe they go on your store? 😁
This could sound like a stupid question but chemistry wise does it not matter when “forming” aqua regia even with the addition of the sulfuric acid. You’ll still have AR just with sulfuric acid included or is it technically something else?
Not sure. The sulfuric hurts nothing. It combines with the lead, if any is present, forming lead sulfate that can be filtered out. I don’t think it causes any other compounds in the AR
Thank you for answering my question, you are a great master in this field, and you explain beautifully how to use acids and combine them with each other, I learned a lot from you. Thank you sir.
A note about the "honeycomb" structure you were looking for in your nitric acid etched alloy sample. At the moment of solidification of the alloy, silver and gold were thoroughly mixed: gold atoms scattered among silver atoms). And in this state it suddenly "froze". Therefore, the structure of gold, even if it resembled a honeycomb, the characteristic size of this structure would be in the order of the distance between gold atoms in the alloy (i.e. in the order of nanometers), with no chance of observing it in an optical microscope. You would need to use an electron microscope.
The college has an SEC. I know the math professor. He may be able to hook me up with the science professor so we can look at it properly. I’ll make a video of it.
Hello Sreetips, I have little question. Some time ago I see one of your video where you talked about something like "why collecting gold" and not other metals. I remember that you show it in periodic table but I am unable to find this video again. Can you help me please?
Hi sreetips... Just wondering what would happen if you immediately went to stump out after the double refine... It looked like some gold was in the filter and wondering if your yield would be a fraction higher if you had not filtered after the double refine
So I have to ask... that brown powder is gold, does it occur in nature like that? Or is only through a chemical process? I find that exact same color inside quartz sometimes. I wonder if I'm looking right at gold and don't know it?! I usually dismiss it as dirt...
I love the way the dissolved gold with ice in it looks like a big ol' beaker of Tang! I'm sure it'd taste horribly metallic and burn your mouth, but it sure looks tasty. 🤣
what the hell is that reddish contaminant? it crashes out of solution with the gold when you use SMB, and it gets dissolved in aqua-regia but not in pure hydrocoric, or am i getting this wrong?
Great video. A stunning bar! Your yield was a bit off from what you calculated. Probably went over while pouring out the waste solutions? That’s like having a piggy bank!
You said that you were pouring waste into the waste container but, you poured some gold oxide with water and with HCl into the container. Very pretty colors but check out that waste container for brown stuff, I'm sure there's some in there!
If you want to see interesting structures in gold, Try melting some into a button. Now, take that button and dissolve the top (outer) layer. If you have done this, you should see with your naked eye, a crystalline structure appear on the surface of the button. Turning the button in your hand, you will see light reflecting off the crystals in very unique patterns. Using a microscope on this you may see it better.
@@sreetips I actually might purchase some to help remove a stump that is in my yard, I wonder if it works as well for that purpose as it does for gold refining!
@@sreetips would there not be much value in those knowing there is gold on them? Obviously tiny scale, but gold none the less, especially considering you are going to be burning the filters up anyway? I've just been curious about that for a long time. Or does the stanis consume the gold.
No, it’s like throwing gold away. I could have saved them all along and made a video about refining them. I bet I’ve thrown away a half ounce of gold over the years. I’ll stay putting them in a container and save them.
Yes, it goes into my temporary waste container. I allow it to settle then recover the pure gold. None of it gets lost. I recovery every bit of the gold.
Sreetips, if you would be up to it, get ahold of a high powered microscope, either a University, or a jeweler might provide the opportunity. That would definitely be really awesome to see, and I think you would absolutely agree! Great attempt!
Sir, that is smart, that you have a refrigerator in your lab. This way the family refrigerator will not get chemical containments. Well, I gotta get one too. Lol 👍👍
You might remember I left a comment about a week ago about the video continuously buffering and not playing? Well, this video was doing that tonight, I changed from firefox, to chrome & it came up, no problems. Have you thought of uploading your videos to Rumble, as well?
You can’t fool me your that cleaver Land Shark .. sreetips you know and I know what that looks like lol that looks like a glop of excrement.

Hi sir.... when I dissolve 10 gram of gold powder to refine it by aqua regia there is some of yellow precipitate appears in solution .. please what's this yellow precipitate... Thanks my friend
I'm always thinking about the silver cell at work in the background. Slowly producing that pure silver crystal. However, the power supply presents questions because of it's nature of design. The problem is that this type of dc power supply is producing an alternating current within the dc output. It utilizes diodes to create the dc output but those diodes are switching on and off thus creating a very destructive alternating current which has a cleaning effect of sorts resulting in very fine particle separation counter productive to the production. I initially thought about placing a few blocking diodes in the wiring between the power supply and anode which gave way to also adding a blocking diode to the cathode wiring. However, the end result is finer and finer alternating current. The diodes just can't prevent it. I decided that an optimum dc power power supply for this cell operating at 3.5 vdc would be a lithium battery or several arranged in parallel. In all reality just one large prismatic cell plate LIFEP04 / LiFe is perfect. Okay, the cell eliminates the alternating current from the silver cell. The single LiFe prismatic cell is economic, readily available and has a twenty year service life. An average size cell produces 100 amps so it will run at 3 amps for 33 hours. It will need to be charged by a solar panel. However, a solar charge controller just placed back to alternating current into the silver cell circuit. Isolation of the pure dc supply ( the prismatic cell) from the charging control is necessary. As I've explored already this can't be accomplished by adding diodes. So, the dc power supply LiFe prismatic cell must be autonomous, completely seperated from a charger. Swapping out the low state of charge cell with an alternate charged cell will accomplish this. Interesting is the photovoltaic module / solar cell. The PV cell produces a perfect dc current without any alternating current. So, six cells at .6 vdc connected in series provides us with 3.6 vdc pure. No diodes. 🌺 Aloha
We could use two dc battery configs. Use one to power the cell while the other charges. The configuration that I run now is satisfactory because the silver assays at very high purity. Thanks for this excellent input.

I heard from a precious metals buying/selling/refining company in my neck of the woods in France that they lost 1 kilogram of gold powder because it sublimated when they poured it into their furnace. It struck me as so odd. I know that you have to be careful with the oxyacetylene torch, hence why you dance around the powder on the rim of the melt dish, but I didn't think that a typical furnace could do it. If the story is true, that's the most expensive mistake I've heard about in the refining world!
Ouch. There are losses all along the way when refining the gold. The trick is to minimize these losses. This will depend on the the skill and technique used by the refiner.
I have a question. When you are down to cement copper out of your waste buckets, why are you not using this cement-copper, to cement out silver? wouldn't it be more sustainable? And why are you not using all different metals to cement out direct every metal above it? Like using silver to cement out gold, then using the next metal to cement out silver and so on. On every run you can use the metal again. i am not a chemist so have some sympathy if my questions maybe stupit or answered in another video. I didnt watched all of them by now
The copper in the waste bucket is contaminated with other metals. I can buy clean copper for refining. It’s cheap and plentiful. Copper is useful for refining precious metals. But after that, it’s considered waste.
That honeycomb structure is based on the atoms and molecular weight not big chunks it'll be very difficult to see with the naked eye or microscope but you can see with an electron microscope
after watching many of your videos I haven't heard you mention this... but I was wondering if gold laden liquid weighs more than basic/normal liquid... for example, would 100 ml of gold bearing liquid weigh more than 100 ml of distilled water? it was just a thought that popped into my head while watching you put the gold concentrates into solutions with the acids.
I'm not sure if your microscope is high powered enough to see down to the molecular level
Yeah the camera zoom seems similar to the microscope power.
Yeah. Doesn't really look like the kind of operation that can afford a Scanning Electron Microscope. But maybe someday! @streetips where do we donate?

That silver cement process is incredibly fascinating.
These chemical processes you do with precious metals helps me to better understand the chemistry of geological formations of metals in their various states. Like how gold is made in the earth and then gets deposited in different places.

Gold is not made in the earth. It is made in stars. All the gold on earth is here as a result of super novas and cosmic impacts.
@@enkidu9705 I,m reaching for the stars now.
@@enkidu9705 , God made the gold. I'm talking about the geological data that talks about gold coming from deep within the earth in lava and or geothermal fluids that deposit gold in rocks or in nuggets near the surface.
I never understood that gold could be in solution until I saw. Sreetips do it . Then it mad sense to me how gold could be in different forms .
@@jimwednt1229 BS god did not make the gold. It is the result of cosmic forces and not divine influence. Keep your religion and science separate.
@@Alex-kp3hr can you PROVE he didn't ?
I'm so confused; any thoughts: If the inquartation gold is poured into plates or just placed into filter baskets and copper plates or filter baskets were alternated. Then if the series connection of plates or baskets between the different potential plates or baskets suspended in electrolyte would create an energy producing battery. Between the anodes and cathodes the silver will move from the gold through the electrolyte and attach to the copper plates. The completed reaction purifies the gold while producing energy as electricity as opposed to it as heat. I wonder how much potential electrical energy each cell of a silver gold - copper battery compares to a lithium iron phosphate 3.5 volts per cell. And I wonder what if nitric electrolyte were substituted with dry electrolyte?
I really like thinking about the silver cell too. Mostly I wonder about how the power supply can only control the voltage. In this silver cell system the current flow is limited to the resistance. Apparently, a relatively low voltage is desirable and the amperage becomes a product of the resistance of the electrolyte. What would result from maintaining the low voltage but increasing the current amperage? Would the crystal size differ? Would the speed and deposition rate change? How would placing a resistance load into the circuit on either the anode or cathode pos/neg wiring control the current amperage? Would the increase in the circuit amperage best be controlled by multiple LED's or resistors twisted together in parallel or would a variable potentiometer like a radio volume pot be better? Since increasing the electrolytic silver cell amperage while maintaining the low voltage provides more control of the production I wonder what effect occurs when decreasing the cell voltage to 1.5 volts while increasing the circuit amperage / load to 5 amperes produces?

I’d like to see a video of that
Breaking bad 2 gold refining edition
Hey I have a question. I love your videos especially the crystallized silver. Can you do the same to gold like making crystalized gold?
Yes
He actually did make it atleast once, but the amount of gold that you need to have in the operation is fairly big.
Some of the bigger mints do this for their high purity gold coins, as a final refining step.
Lovely video as always. Are there any tips for getting started on the melting process of precious metals, such as what gas to use, flux, best types of crucibles, and insuring there isn’t impure substances?
All good points. Each is covered in my videos
I think it's notable that the inquarted gold has formed these little nugget like clumps that look nearly identical to some natural nuggets.
I wonder why .
As for seeing the honeycomb structure, you probably just need a more powerful microscope .
I'm very curious to see a drop of the gold in solution on a slide under a very powerful microscope. 🤔
Cool video, man . Thank you 👍
you need to place it between two pieces of glass so it is flat, the 3d structure otherwise causes the camera in the microscope to fall out of focus.....
I’ll take it to the college and we can look under the scanning electron microscope.
I always wondered if agitation while precipitating the gold out would form less small particles and hence less temporary"loss" in the waste bucket. Even if you will recover it later on it might make the cleaning of the precipitate easier?!
Do you think it's worth a try?
Yes, that plus boiling to get the gold to settle out completely.
My guess on the mystery chunk is a gemstone. As to what it may have been, your guess is probably better than mine. As for what that reddish discoloration after 2nd AR refining, I wonder if there may have been enough free acid in the solution to start pulling gold back....?
May have been an opal. The red - that was just baffling. Stuff like that never happens. Only when I’m shooting video. Like the refining gods are frowning.
If your ring were a lower karat it would have been something more like reduction guilding which is where you allowed to work for a short period of time as a surface treatment to give it the appearance of 24 karat.
Have you ever done anything like that?
It might be something to bring your experience to bear on and perfect the details through your vast knowledge so we can all get another little piece of the puzzle to add to our understanding of all things golden that would also be very interesting to see at the microscopic level
It would be amazing to see the gold precipitate grains under the microscope. I always wondered just how small they were.
Do you have a formula or price list that you use to help you in determining how much to pay for karat gold from garage sales and other places you find items? I would image it has something to do with the karat and weight of the item. Also, do you happen to know your total expense amount for a processed gram of gold? Thank you!
App called “Scrap Gold Pro”
@@sreetips that's interesting, I didn't realize there were apps out there for that kind of thing
Hello, professor, please show a program related to the extraction of precious metals from mineral soils. I will be grateful.
I’ve tried extractions from soil, tailings. They are time consuming, produce little to no yield. And create lots of waste that must be treated prior to disposal. Unfortunately, it’s just not worth the time and effort.
@@sreetips You are right, but where I live, most of the extraction work is done from the soil and I am very uneducated in this regard ☺☺☺☺
What are the chances the white particles are pieces of ceramic from one of your overflow crockery or melt dish?
Quite possible
I suggest a collaboration with Alpha Phoenix, he has access to atomic scale microscopy, and I bet it would be a really interesting collaboration!
It did have the appearance of a porous surface, but the holes are way too small to see with that or maybe any optical microscope. It was still worth the try. great video as always.
Another beautiful bar of gold, and video.
Carson makes a nice 100x-250x handheld microscope for around ten to twenty dollars that could do a way better job at showing the finer details. It also comes with a slide for the smaller stuff.
I think this may be the most informative video on refining
what do you do with the final rinse liquid? is there still gold?
Yes, it goes in my stock pot.
I would love to see you do an experiment on your rinsing, particularly how much gold you lose during your normal "rinse cycle" when you rinse off the pure gold. My thought is if you lose a tenth of a gram per rinse, 10 rinses equal a gram of gold. You could take some triple refined gold you know has no contamination, or at least a negligible amount, weigh it to the hundredth of a gram, refine two more times, melt into a bar and reweigh. Take note of how many rinses and what might be in the filter. It would give you an idea of how much you lose per refining so you can know how much to adjust your yield, how long before you need to clean container, etc.
I believe you more or less have your answer in this video here:
czcams.com/video/RXkP-6QsL5s/video.html
In that video Sreetips recover the solid gold particles at the bottom of five containers with rinsing solution, or gold refining waste. The solution gets poured into the stock pot and the solid particles gets recovered with aqua regia and SMB. The result is 16 grams of gold from the five containers, which I assume is more or less the result of five previous refinings. If my assumptions are correct, it would mean that Sreetips has lost 3.2 grams of gold per refining. It would be slightly more if we include what gets poured into the stock pot. In the video above (Inquarted Gold Under The Microscope) Sreetips expected a yield of 119.1 grams and got 116.7 grams, which means a loss of 2.4 grams. I think we can safely assume that most of the gold that is expected from each refining but never reaches the final yield, actually ends up in the refining waste, which is later recovered.
With that said, I would love to see a video like the one i linked to above (Gold Recovery from the Waste Containers) again, with the added bonus of including the numbers from what Sreetips was expecting from the refinings compared with the actual yields.
@@HenricLassesson issue is there are too many assumptions of the issue which without actually counting and knowing how much you start with. Remember the scientific method. We have the hypothesis. We need to control as many variables as possible. I'm an avid watcher and know that Sreetips doesn't film all of his refinings. Besides, don't you want more content?
@@beauhodges7957 Of course; I would love more content. That's why I suggested the type of content I would like to see more of. I also know of the scientific method(s). I believe that your setup of an experiment could be quite beneficial. We can learn a lot from that. I do, however, see a few problems:
1) Refining gold that is already triple refined would be a waste of time and chemicals for Sreetips when he could be focusing on refining other stuff that will actually result in some extra money. My suggestion would be a part of his everyday refining anyway.
2) We don't know if the rinsing of the triple refined stuff will result in the same amount of lost gold as rinsing of inquarted gold jewelry. Less pure gold could very well result in more nano and mikro particles that will rinse off with the water, i.e. greater loss.
3) In order to account for variability, it would be best if the experiment would be tested at least three times (more if there is large variability). This comes back to my first point. Wasting time and chemicals once is one thing, but doing it three times would be even more wasteful. If the experiment, instead, is performed as a part of what Sreetips does anyway (refinings that are off camera) then it will not be a problem to account for variability. The video I linked to had five containers and it would not surprise me if Sreetips has some other results in his notes somewhere.
@@HenricLassesson true. My point with the triple refined gold was to remove contamination from the equation to limit that variable from the overall question. Start with a known amount, count rinses, dry product, cast into bar and reweigh. It would give a great idea how much is lost during the rinsing process with pure gold. I think we are not on the same page.
My assumption on your comments is you are considering the total process, and all of the gold combined. Those videos where he cleaned out his "savings account" in the bottom of those containers we was fun to watch. (I always watch the day he releases.) In that case you are absolutely correct that there is enough in prior videos to make several assumptions about how much is lost.
What I am considering is single refinings. You make excellent points, which would only improve the result. My thought process is to determine for each individual refining, how much is lost to rinsing? Then you can make certain assumptions about each subsequent refining you do how much you lose for each additional refining after the first. My thought process is to gather data to suggest that if you know you will lose a specific amount of gold in each refining, is the 2nd, 3rd, etc. actually worth the chemicals to refine? Hypothetically, if you lose 1 gram per refining to the stock pot, is that worth the additional chemicals to do a second refining. Or a third. If you lose .5 gram, that is $28 usd as of right now.
I think no matter which way it is considered, I do want to see more stock pot videos. Super interesting.
@@beauhodges7957 No, I think I do understand what you mean. We are both talking about the rinse liquid being poured off at 21:23 right? We both want to know how much gold is being poured off at that moment. By the way, it’s not lost forever just stored for a later occasion. By using gold that is already triple refined, as you suggested, it will give us a precise amount of what is poured off from that very pure sample. But the question is if it will give us the answer to how much that gets poured off from a less pure sample, which is what we actually want to know. Or that is at least what I would like to know. I don’t know if the amount being poured off is affected by the purity of the gold or not. It could be. It will be affected by the amount of tiny particles suspended in the liquid. You have noticed the brown color in the first few rinses right? That is due to the amount of really small particles that didn’t have time to sink to the bottom. The size of the particles could be affected by several things, where trace amounts of other metals (when SMB is added) could be one factor. The concentration and temperature of the gold solution (when SMB is added) could be other factors that affect the particle size. The loss during rinsing would also be affected by the total amount of gold that is being rinsed and by the speed of the rinse (is Sreerips in a hurry?). In other words, there are many factors influencing the result, which makes it almost random. This is why I’m voting for testing this several times (under “normal” conditions) and taking an average of many trials instead of testing it very precisely once.
Also.... These last several chunky bars you have made have been quite spectacular. Any thoughts on doing some silver bars? Maybe with a bit of silver crystal from your electrolytic cell? ..... Maybe they go on your store? 😁
Good idea. But they take so much work!
I've had an idea.
Would you like provide a TEM or SEM image of all your type of metals in all stages?
Isn't it interested?
Yes
This could sound like a stupid question but chemistry wise does it not matter when “forming” aqua regia even with the addition of the sulfuric acid. You’ll still have AR just with sulfuric acid included or is it technically something else?
Not sure. The sulfuric hurts nothing. It combines with the lead, if any is present, forming lead sulfate that can be filtered out. I don’t think it causes any other compounds in the AR
@@sreetips thank you so much I’ve learned so much from you and your channel that I can’t even put it into words.
If possible, make a video on the subject of gold recovery using sodium cyanide, and how to recover gold from gold rock or soil.
I don’t have any cyanide. None of the refiners that I learned from used cyanide. No experience with rock or soil. Sorry
Thank you for answering my question, you are a great master in this field, and you explain beautifully how to use acids and combine them with each other, I learned a lot from you. Thank you sir.
A note about the "honeycomb" structure you were looking for in your nitric acid etched alloy sample. At the moment of solidification of the alloy, silver and gold were thoroughly mixed: gold atoms scattered among silver atoms). And in this state it suddenly "froze". Therefore, the structure of gold, even if it resembled a honeycomb, the characteristic size of this structure would be in the order of the distance between gold atoms in the alloy (i.e. in the order of nanometers), with no chance of observing it in an optical microscope. You would need to use an electron microscope.
The college has an SEC. I know the math professor. He may be able to hook me up with the science professor so we can look at it properly. I’ll make a video of it.
Hello Sreetips, I have little question. Some time ago I see one of your video where you talked about something like "why collecting gold" and not other metals. I remember that you show it in periodic table but I am unable to find this video again. Can you help me please?
I can’t remember.
Most beautiful inanimate thing I've ever seen and I know that seeing on a screen doesn't do it justice.
Hey Sreetips. I got ripped off and bought a couple fake gold bars. Wonder if it would be worth extracting any of the actual gold they have?
Maybe I can send the lot to you so people can see how good the fakes have gotten
That’s terrible news.
That AR must be really syrupy judging by the way it coats those beakers.
Very concentrated 👍
Can you look at some of the silver crystal under the microscope? Or even some gold crystal next time you make a gold cell?
Hi sreetips... Just wondering what would happen if you immediately went to stump out after the double refine... It looked like some gold was in the filter and wondering if your yield would be a fraction higher if you had not filtered after the double refine
Traces only, probably not enough to affect the yield.
What is the consistancy of the gold to the touch? Is it like holding mud between your fingers?
I’ve never tried it
@@sreetips I bet its either like mud, or maybe spongy. Id love to see what it feels life! Fascinating
Awesome such beautiful gold excellent video as always thank you for sharing five stars sir
So I have to ask... that brown powder is gold, does it occur in nature like that? Or is only through a chemical process? I find that exact same color inside quartz sometimes. I wonder if I'm looking right at gold and don't know it?! I usually dismiss it as dirt...
Gold occurs naturally in quartz
@@sreetips But can it look brown in quartz like it looked right before you smelted it? Or does it always look shiny in quartz?
Not sure about that.
I love the way the dissolved gold with ice in it looks like a big ol' beaker of Tang! I'm sure it'd taste horribly metallic and burn your mouth, but it sure looks tasty. 🤣
Lol it looks like army ration orange "screech" lol
what the hell is that reddish contaminant?
it crashes out of solution with the gold when you use SMB, and it gets dissolved in aqua-regia but not in pure hydrocoric, or am i getting this wrong?
Who knows
Great video. A stunning bar! Your yield was a bit off from what you calculated. Probably went over while pouring out the waste solutions? That’s like having a piggy bank!
The calculated yield will almost always be greater than the actual yield. That’s because 14k gold can be as low as 13.5k and still be stamped 14k

Here is a question , what would happen to Gold in solution if you poured in stannous Chloride to it ? Would it drop out the gold ?
Possibly.
Honey comb structure is on atomic level. In order out see it you should use scanning tunneling microscope.
Looks like a piece of chocolate that's been in your pocket all day during a hot summer
💩
You said that you were pouring waste into the waste container but, you poured some gold oxide with water and with HCl into the container. Very pretty colors but check out that waste container for brown stuff, I'm sure there's some in there!
It’s full of gold. And I’ll recover it later.
Just what I needed.
If you want to see interesting structures in gold, Try melting some into a button. Now, take that button and dissolve the top (outer) layer. If you have done this, you should see with your naked eye, a crystalline structure appear on the surface of the button. Turning the button in your hand, you will see light reflecting off the crystals in very unique patterns. Using a microscope on this you may see it better.
Does anyone at the hardware store ever wonder why you purchase so much Stump Out? Good video as always, air!
Yes, and I told them.

I always wonder if you put the stanis test strips in with your used filters to extract the gold from those aswell?
No, I toss them
@@sreetips would there not be much value in those knowing there is gold on them? Obviously tiny scale, but gold none the less, especially considering you are going to be burning the filters up anyway? I've just been curious about that for a long time. Or does the stanis consume the gold.
No, it’s like throwing gold away. I could have saved them all along and made a video about refining them. I bet I’ve thrown away a half ounce of gold over the years. I’ll stay putting them in a container and save them.
@@sreetips good to know. Like I say, I've always wondered. Thank you for the response and the great videos as always
Isn't some of the precipitate being lost each time you shake up the beaker and pour off the cloudy solution into the waste beaker?
Yes, it goes into my temporary waste container. I allow it to settle then recover the pure gold. None of it gets lost. I recovery every bit of the gold.
@@sreetips Very cool
That should Money Heist do. Make those goldbars as liquid gold.

No sure if anyone has noticed 14:58 theres is a orb that travels from where his arm is to the left of the screen.
I had the camera light on. That was a dust particle that floated by during the shot.
Was that lead that precipitated out at the bottom of the beaker?
No, it was in there before I dissolved the gold

I'm always thinking about the silver cell at work in the background. Slowly producing that pure silver crystal. However, the power supply presents questions because of it's nature of design. The problem is that this type of dc power supply is producing an alternating current within the dc output. It utilizes diodes to create the dc output but those diodes are switching on and off thus creating a very destructive alternating current which has a cleaning effect of sorts resulting in very fine particle separation counter productive to the production. I initially thought about placing a few blocking diodes in the wiring between the power supply and anode which gave way to also adding a blocking diode to the cathode wiring. However, the end result is finer and finer alternating current. The diodes just can't prevent it. I decided that an optimum dc power power supply for this cell operating at 3.5 vdc would be a lithium battery or several arranged in parallel. In all reality just one large prismatic cell plate LIFEP04 / LiFe is perfect. Okay, the cell eliminates the alternating current from the silver cell. The single LiFe prismatic cell is economic, readily available and has a twenty year service life. An average size cell produces 100 amps so it will run at 3 amps for 33 hours. It will need to be charged by a solar panel. However, a solar charge controller just placed back to alternating current into the silver cell circuit. Isolation of the pure dc supply ( the prismatic cell) from the charging control is necessary. As I've explored already this can't be accomplished by adding diodes. So, the dc power supply LiFe prismatic cell must be autonomous, completely seperated from a charger.
Swapping out the low state of charge cell with an alternate charged cell will accomplish this.
Interesting is the photovoltaic module / solar cell. The PV cell produces a perfect dc current without any alternating current. So, six cells at .6 vdc connected in series provides us with 3.6 vdc pure. No diodes.
🌺 Aloha
We could use two dc battery configs. Use one to power the cell while the other charges. The configuration that I run now is satisfactory because the silver assays at very high purity. Thanks for this excellent input.

@@sreetips thank you
I heard from a precious metals buying/selling/refining company in my neck of the woods in France that they lost 1 kilogram of gold powder because it sublimated when they poured it into their furnace. It struck me as so odd. I know that you have to be careful with the oxyacetylene torch, hence why you dance around the powder on the rim of the melt dish, but I didn't think that a typical furnace could do it. If the story is true, that's the most expensive mistake I've heard about in the refining world!
Ouch. There are losses all along the way when refining the gold. The trick is to minimize these losses. This will depend on the the skill and technique used by the refiner.
I have a question.
When you are down to cement copper out of your waste buckets, why are you not using this cement-copper, to cement out silver? wouldn't it be more sustainable? And why are you not using all different metals to cement out direct every metal above it? Like using silver to cement out gold, then using the next metal to cement out silver and so on. On every run you can use the metal again.
i am not a chemist so have some sympathy if my questions maybe stupit or answered in another video.
I didnt watched all of them by now
The copper in the waste bucket is contaminated with other metals. I can buy clean copper for refining. It’s cheap and plentiful. Copper is useful for refining precious metals. But after that, it’s considered waste.
@@sreetips ok, but if the copper was clean you can theoretical use it again right?
I’ve never tried. I don’t know.

That honeycomb structure is based on the atoms and molecular weight not big chunks it'll be very difficult to see with the naked eye or microscope but you can see with an electron microscope
after watching many of your videos I haven't heard you mention this... but I was wondering if gold laden liquid weighs more than basic/normal liquid... for example, would 100 ml of gold bearing liquid weigh more than 100 ml of distilled water?
it was just a thought that popped into my head while watching you put the gold concentrates into solutions with the acids.
The answer is yes. I did the experiment in my multi-part video on the “Wohlwill Process” listed on my channel.
Of course! and it's proportional to the molar strength of the solution. More moles of Au per 100ml in solution. the more mass.
