I have no idea why a random cultured hobby machinist guy like myself is so absorbed into watching a professional do all this interesting chemistry and metalworking wizardry to make forbidden orange juice, but here we are.
"Forbidden orange juice" NGL it looks really good! I never really liked the color of gold before. I always preferred silver (and white gold, but not yellow). Since I've been watching sreetips for a couple of years now, I'm really loving the pure gold that comes at the end of his videos! And the "forbidden orange juice" is probably one of my all-time favorite colors now. It's so beautiful.
This! I think one of the most fascinating videos from the various chemistry related creators I follow is when they do bulk processing of waste that they have generated over long spans of time
Yeah. I was just thinking "I wonder if sreetips has already made a video of refining gold from his waste containers" and then here's your comment. EDIT: I looked it up. He actually did refining from his waste containers just a few months ago.
I feel no need, no need for speed! We love the process and the in-depth videos. I could watch you do the same sequence over and over. I look forward to the further refining of the silver and waste as well!
I love watching u work and your voice is so calming when u do it but I also learn alot listening to your videos thank u for showing how inquotation works...
Answer to "why not reuse silver shot for gold inquarting?" answered: I've asked that question too and he actually answered it in this video. As you saw, there was some white gold in the mix that contains a more higher concertation of platinum group medals (such as palladium or platinum) that came out in the silver nitrate as a more green colour. As Sreetips is looking for high purity gold, reusing the same silver shot over and over when inquarting, will eventually have a higher concentration of those medals if reused overtime, leading to a possible lesser quality of gold that is more likely to have those heavier metals in the final refining.
'White' gold is going to be rhodium plated gold, and that'll be picked up in the filter paper after the nitric acid boils. If he has any platinum in the original jewelry, that'd be caught on the filter paper too. Any palladium would be in the silver nitrate stock pot. If I understand correctly, he ran something like 40 pounds (or was it 40 kilograms?!?) of silver shot through his silver cell and when he worked up the slimes from the anode bags, he only got several grams of palladium. On that basis, unless he had one or two pieces of high palladium content jewelry, he'd never run afoul of any worry about palladium contaminating his silver. If he inquarted several runs with cement silver, all he'd do is make his palladium workup more productive, at the same time consuming less pure silver crystal to make up his silver cell electrolyte.
@@AndrewStAmand That’s what he’s doing now and why he’s doing it like that. Seeing that there is no AuPd jewelry alloy, the simple method to prevent a Pd rich item from getting the melt is to sort ‘white’ items from the jewelry.
Thank you SOOO MUCH for sharing your VAST KNOWLEDGE of Chemistry involving Precious Metals/Alloys!!! I feel like I have such a stronger understanding of the processes after watching/listening/learning from your instructional videos!! From simple things like: just what exactly Borax is doing to the final stages of your Purification & Pour, instead of just simply knowing tbe fact that Borax must be added and what point it gets added. It is much more satisfactory to have a full understanding of WHY!!

Hello from a UK subscriber 🇬🇧. Great videos, very meticulous and a detailed explanation as you proceed . The electrolytic silver cell fascinates me, silver being my favourite precious metal. Magical.
12:40 Hello. I always watching your videos to understand this process. I noticed that you don't neutralize the nitric acid before adding the SMB. How does SMB precipitate gold if there are acids, aqua regia? 😊Thanks in advance🙂
Excess hydrochloric acid is not a problem. Excess nitric is a big problem because the gold will redissolve just as fast as it precipitates until all the excess nitric gets consumed. I add just the right amount of nitric to just dissolve the gold. That way, there’s no excess nitric to neutralize. It’s called incremental nitric dosing. One of the most valuable refining techniques I’ve ever learned. Second only to inquarting with silver.
That was another enjoyable refining video. I hope you don’t get in trouble with Mrs Sreetips for the missing forks at the dinner table. :) Happy Easter!!
I very much like how you preheated your stir rod, I do wish someone would have warned me about not doing that and causing a steam explosion haha.

@@jeremiah1528 thank you. A man, who was probably feeling quite anxious, yelled at my friends and I as we were walking down the sidewalk, since we were in his way. I hope he's doing alright.
I am unusually curious about your watch. If you come across so much jewelry and watches you could have anything you want. Is this particular watch sentimental or is it real gold like most of them aren't anymore?
I’ve been watching your videos for a long time and I just now realize I wasn’t subscribed😰 I don’t know if you already have a video on this, but do you think you can make a masterclass on how you refine gold? How to calculate yield and how much to inquart, how to measure chemicals? I think there are a lot of people including me who would love to do this with the scrap we have at home! Love your videos!
Thanks for the subscription. Each one of my videos on gold refining cover all the points that you listed. All you have to do is watch the videos and take notes. I’ve left nothing out. But make sure you do this in a fume hood. No way to safely do these reactions without one.
shalom from norway ❤️🇳🇴 if you put something like a cloth at the bottom of the water you use to cool the bar , you might be able to avoid the mark at the corner.
I had what I thought was a clever idea the other day. Get an end mill. Then cast bar’s with the silver/gold metal. Put the bars in the end mill and shave them down. I would imagine the filings would be easier to process than the larger chunks therefore using less acid. I could be way off base. Just a thought
Just out of curiosity, could you maybe weigh your gold into solution against the same mls of water. Dont think it would achieve anything, just be interesting to see the difference. Really enjoy your videos, super relaxing.
You don't like gold ??? You must be in love with those green things that are about to collapse any minute. So I guess you don't like financial security...
Something I have wondered after watching a few sreetips gold refining videos is why not do an ammonia rinse before the final melt? Ammonia will dissolve (complex) silver chloride to get rid of any that slips through the filter before precipitation. It's an extra step but much less effort/cost than a second dissolve and precipitation. Maybe you could do a video where you split a batch and double refined one half and ammonia rinsed the other?
I hate working with ammonia. I’ve excluded it unless it’s absolutely necessary such as when I use it to dissolve palladium for refining. And even then I do it outdoors. Ammonia seems to be even more corrosive than the acids I use. It’s ruined more equipment than anything else.
Thank you for not only the content but the extremely valuable information Mr.Sreetips. I have a question though, when you melt the gold into bars, why do you turn the torches off while the flame is on the gold vs removing them to first? Wont it avoid the ripple lines if you do? (forgot what you called them in a previous video)
I keep the flame on the gold as I pour to prevent the air for getting to it as it freezes in the mold. It’s called a reducing flame. This prevents a frosty appearance from forming on the surface of the bar.
Hello Sreetips, I find your videos very interesting. I am new to this and I just watched Silver Refining How To Make Electrolyte For The Silver Cell. What I'm trying to wrap my head around is this, if one starts with a silver bar and dissolves it to make the initial silver nitrate solution to begin the silver cell process, where does the net silver come come from?
Sterling silver flatware and scrap 925 jewelry items. I buy flatware at estate sales - cheap. My wife get 925 scrap jewelry from yard sales - very cheap. I use the sterling flatware and scrap 925 jewelry in my gold refining process. Silver is a by-product of gold refining. Once it’s been extracted from the gold, I reduce the silver on copper and recover the silver powder, melt it into granules, then run it through my silver cell. I add the silver granules over a ten to fifteen day period to the anode basket of my silver cell. I pass an electric current through the impure silver in the anode basket. The current flow dissolves the silver and the silver ions pass through the filter, into the electrolyte, and plate out on the inside of the stainless steel bowl (the cathode) as high purity elemental silver. I only get out what I put in, less impurities.
Hey bud love the shows keep up good work question I've never refined my my gold refining solutions yet I was wondering what the growth is coming off the copper
I know people have asked if you can use cement silver to augment the gold. But, you should be able to use a small quantity of the pure silver crystals instead of sterling silver. Because you'd use a known quantity with known properties, by the time it gets back to goingbthrough the silver cell you should have very little pgm's. Unless you believe the potential loss of silver is not worth the risk of using your pure silver crystals.
Using pure silver to inquart would be like taking a step backwards because it already been through the silver cell. Sterling/925 silver is the best for inquarting. Sterling flatware is the best of all sterling (in my opinion) because it’s so clean.
Question for you. Let's say I was in different stages with multiple processes of gold refining and had to quit for awhile without finishing up. The different ways of doing it incure the different acids you use. If you leave them sit in the liquid form and the solution, whatever it is, evaporates completely. Does the gold go with it or is it left in the residue that's left? Thanks
The gold will still be there even if it evaporates to dryness. To hydrate and re-dissolve the solids simply add hydrochloric acid. The book says to add a few crystals of sodium chlorate if bits of metallic gold are observed, to redissolve them. Sodium chlorate and hydrochloric acid form chlorine gas. Chlorine gas will dissolve just about any metal.
Love it. But I've got a dumb question for you, have you ever used your cement silver or your silver shot instead of sterling silver? And do you think it would work?
Would it save you any time if you had a second burner getting your chemicals/distilled water up to twmp off camera so they could work a bit faster? Just curious. Love the videos!
Could you stick chopped up sterling silver cutlery in the diode basket instead of silver shot? I mean, it would be less efficient for certain, but would it work? If all the resources you had were the means to make a silver cell and some sterling silver cutlery, could you refine it?
Yes, it can go in. But the electrolyte would quickly become saturated with copper. For electrolytic refining it’s best to use silver that’s already relatively pure.
i wonder what the contamination is and what it was from, maybe the palladium from the white gold? platinum group metals are about the only things that will survive the aqua regia with the gold right?
A single refining with no tweaking before the melt - could be a trace of copper. Copper is a junk metal that will foul the surface of precious metals during an ingot pour. Even in just trace amounts.
I was wondering, if you just calculated weight and inquarted gold scrap and pour it into shot, could it possibly be more efficient process wise to just keep doing that and then just weigh out a set amount of inquarted gold each time you refine so that you don't repeat steps or use more chemicals for varying yields? Seems like the steps take the same amount of time wether you are refining ten grams or ten oz. I'm sure someone in the audience can answer this who has experience. Maybe I'm not thinking of something.
The steps are the same for 10 grams as for ten ounces. But the time is not. I refined almost 25 Troy ounces once in a single batch. It was terribly awkward and exceeded the capacity of my small hobby operation.
I just wonder how much the scrap that he started with cost him and the final value of the gold (and silver?) is. Seems like he's turning basically a few hundred dollars worth of near junk into 1.5-8k$ bar.
They sell hand-held vacuum pumps that work pretty good but require constant pumping by hand that could get tiring. I’ve made a video on building a reliable vacuum system. It’s posted on my channel.
Anyone else become fascinated by the small amounts of gold that were left behind on the crucible and how they might have negatively affected his yield? I saw at least half a gram get away.
it all gets pulled out with future refines, nothing is ever wasted. what's left in the dish will be absorbed with the next melt. even when the dish is no longer good you can recover it from the dish. not sure if he has ever done a old crucible recovery video or not.....
I saw your videos by chance and am mesmerized. Handling and heating all those concentrated acid in a small hood while filming looked very precarious and dangerous so you be careful now. Can you make a video of how you deal with the paper filers and leftover liquids etc? It would be very interesting to see how much gold/silver you recover.
Found this under “gold chloride” on Wikipedia: Gold (III) Chloride, or Auric Chloride, or Chloroauric acid, (all three are names for gold dissolved in acid) with a chemical formula Au2Cl6.
It's just amazing what chemists have come up with. I like how he calculates the amount he should get from the various carats beforehand. BTW I looked up 70 grams of gold price is 4,474 dollars.
Great video. Are these for your private collection or is single refining good enough for top $$ from a refiner? I like to see the occasional SMB bubbler gold drop video - I find those most enjoyable 😀
@@sreetips I've wondered whether you keep your better, more refined gold segregated from the lesser stuff in your stash, or if you mark them somehow to remind yourself which is which. Now, I'm wondering if you ever keep the lesser gold at all.
Can you do a video refining one of those "gold" bars that are sold on eBay? They are just metal melts from computer scrap and have a percent of gold in it.
No, but Ace Hardware sells spectricide stump remover (potassium nitrate) and Rooto Professional Drain Opener (sulfuric acid) and you can make nitric with those.
Sreetips! Quick question, I'm refining some sterling plateware I picked up at an estate sale using the sulfuric acid method in your video about refining with chemicals from the hardware store. The acid has turned black. I'm guessing from the oxidation off the sterling. Will this affect the silver at all? Any tips to keep this happening in the future?
Silver plate is a thin coating of silver over a base metal, usually brass, but sometimes copper. I have no experience with silver plate and sulfuric acid. But either way, the amount of silver contained in silver plated items is very small.

Love it. But I've got a dumb question for you, have you ever used your cement silver or your silver shot instead of sterling silver? And do you think it would work?
No, it’s not recommended.
Your the best
Hey Mr Sreetips! Quick question, why don’t you use a heating mantle with stirring in your reactions? Wouldn’t that be better and faster?
I guess I didn’t think it was necessary.
Would it save you any time if you had a second burner getting your chemicals/distilled water up to twmp off camera so they could work a bit faster? Just curious. Love the videos!
Possibly
Could you stick chopped up sterling silver cutlery in the diode basket instead of silver shot? I mean, it would be less efficient for certain, but would it work? If all the resources you had were the means to make a silver cell and some sterling silver cutlery, could you refine it?
Yes, it can go in. But the electrolyte would quickly become saturated with copper. For electrolytic refining it’s best to use silver that’s already relatively pure.
Thanks! I'm loving the videos and chemistry.
It's just fascinating.
i wonder what the contamination is and what it was from, maybe the palladium from the white gold? platinum group metals are about the only things that will survive the aqua regia with the gold right?
A single refining with no tweaking before the melt - could be a trace of copper. Copper is a junk metal that will foul the surface of precious metals during an ingot pour. Even in just trace amounts.
I was wondering, if you just calculated weight and inquarted gold scrap and pour it into shot, could it possibly be more efficient process wise to just keep doing that and then just weigh out a set amount of inquarted gold each time you refine so that you don't repeat steps or use more chemicals for varying yields? Seems like the steps take the same amount of time wether you are refining ten grams or ten oz.
I'm sure someone in the audience can answer this who has experience. Maybe I'm not thinking of something.
The steps are the same for 10 grams as for ten ounces. But the time is not. I refined almost 25 Troy ounces once in a single batch. It was terribly awkward and exceeded the capacity of my small hobby operation.
I just wonder how much the scrap that he started with cost him and the final value of the gold (and silver?) is. Seems like he's turning basically a few hundred dollars worth of near junk into 1.5-8k$ bar.
Ahh, so this is where all those missing forks have been going
We buy silver from estate sales.
@@sreetips I was wondering where the gold comes from as I'd heard you talk about the silver before.
Grrat videos bro. Having trouble finding a small vacuum for my buchner funnel. Any links. Tried Hvac vacuum which was way to powerful.
They sell hand-held vacuum pumps that work pretty good but require constant pumping by hand that could get tiring. I’ve made a video on building a reliable vacuum system. It’s posted on my channel.
Thank you sir for your info
What's the name of the book you were referring to in the gold refining process?
Refining Precious Metal wastes
Anyone else become fascinated by the small amounts of gold that were left behind on the crucible and how they might have negatively affected his yield? I saw at least half a gram get away.
it all gets pulled out with future refines, nothing is ever wasted.
what's left in the dish will be absorbed with the next melt.
even when the dish is no longer good you can recover it from the dish.
not sure if he has ever done a old crucible recovery video or not.....
That's a great looking bar from scratch in few hours. Slow down on your pours as they could be dangerous.
I saw your videos by chance and am mesmerized. Handling and heating all those concentrated acid in a small hood while filming looked very precarious and dangerous so you be careful now.
Can you make a video of how you deal with the paper filers and leftover liquids etc? It would be very interesting to see how much gold/silver you recover.
I have a video on recovering gold from my filter paper posted on my channel.
I love this channel
What's the chemical formula for gold when it's dissolved in the acid solution?
Found this under “gold chloride” on Wikipedia: Gold (III) Chloride, or Auric Chloride, or Chloroauric acid, (all three are names for gold dissolved in acid) with a chemical formula Au2Cl6.
What’s the rush? Just for giggles or is there an immediate need or buyer available?
Taxes are due
Love it!
It's just amazing what chemists have come up with.
I like how he calculates the amount he should get from the various carats beforehand.
BTW I looked up 70 grams of gold price is 4,474 dollars.
welcome to the Bob Ross of alchemy channel with the one and only sreetips =)
That's amazing.
Wow, over yield on two refinings in a row. You need to find out who is selling you the good stuff and buy em out!
cool stuff.
Nice
Mr sreetips what amp fuse do you run in your silver cell this was also a great video
3 amp
Good job thx you
What is reacting in the silver jar with the nitric you poured at around 7:30?
I’ve got some pieces of sterling silver in there to consume the excess nitric.
Great video. Are these for your private collection or is single refining good enough for top $$ from a refiner? I like to see the occasional SMB bubbler gold drop video - I find those most enjoyable 😀
Taxes are due
@@sreetips I've wondered whether you keep your better, more refined gold segregated from the lesser stuff in your stash, or if you mark them somehow to remind yourself which is which. Now, I'm wondering if you ever keep the lesser gold at all.
One day, after I get out of debt completely, I’ll be able to keep some gold.
Can you do a video refining one of those "gold" bars that are sold on eBay? They are just metal melts from computer scrap and have a percent of gold in it.
I’ve already got one posted on my channel. They are a big rip-off.
His video showed that the total amount of gold contained in about 200 g was so small as to barely even be visible. A few milligrams at most.
@@sreetips Thanks! I'll check it out.
Thanks for that “quiky “ of a refining Sreetips.
Quick question about your watch, is that a piepan date Omega ? How long have you been wearing it?
Yes, Omega Pie Pan. She (Mrs sreetips) got that for me about 5 years ago at an estate sale, $275.
@@sreetips she must have a very good eye.
what is the heat source that you use for melting? It looks like its really fast :o
Oxy/acetylene torch
Your definitely faster then me I remember it would take me days
Do any local stores sell nitric acid ? Like home Depot or ace? Would you happen to know.?
No, but Ace Hardware sells spectricide stump remover (potassium nitrate) and Rooto Professional Drain Opener (sulfuric acid) and you can make nitric with those.
teach me how you edit videos, i just don't get it & it makes me feel so old.
I use Microsoft “Movie Maker.” It’s basic but easy to figure out on your own. Get it then do like I did; start adding footage and learn by doing.
@@sreetips thank you !!
Sreetips! Quick question, I'm refining some sterling plateware I picked up at an estate sale using the sulfuric acid method in your video about refining with chemicals from the hardware store. The acid has turned black. I'm guessing from the oxidation off the sterling. Will this affect the silver at all? Any tips to keep this happening in the future?
I’m no expert but you should just have to reduce it. I’m guessing melting will do that.
Silver plate is a thin coating of silver over a base metal, usually brass, but sometimes copper. I have no experience with silver plate and sulfuric acid. But either way, the amount of silver contained in silver plated items is very small.
Dumb question.... why did you need to quart the gold? Couldn't you have just melted it down and pulled the slag off of it outright?
No, melting the metals causes them to alloy together, not separate.
Very nice. What's the maximum that you can go over with the silver when you mix them? Thank you for sharing this with us six stars sir
Up around 10k (about 40%) and the nitric has trouble penetrating.
@@sreetips thank you sir
Nice video sir...Do you have any gold or silver for sale.?
A few pieces on my eBay site.
10:10 timelapse of me drinking the forbidden orange juice
With all due respect, why don't you use ice when making the initial shot? I'm honestly curious.
Didn’t think of it
Thank you for the response and I hope you and your family have a wonderful Easter weekend.
