Long time watcher. Just wanted to say thank you for the fascinating and somewhat cathartic content over the years. Just one humble fan of many, in this case from Sydney Australia. Greatly appreciate the effort that you go through for all our entertainment.
Same here @sreetips ! I learn SO much just by watching the actual hands-on work of separating the metals via the various processes. "Spectacular" was exactly the word I was thinking when the Au flashed over. This channel was what got me, a machinist/electronics tech, interested in chemistry. Quality Entertainment! Greetings from Hopkinsville, Ky!
This is truly an example of a perfect storm. Mrs. Sreetips is a world class talent when it comes to rummage and estate sales, thrift shops and the odd church or yard sale. And then there's you, with your love of chemistry and obvious talents as demonstrated here. Without realizing it, you two are truly a POWER couple, Senior Chief! My wife is much like yours, but she married a man whose talents are, let's just say, not as useful as Mr. Sreetips. But I keep trying! I figure if I just keep watching these videos enough, I'll one day start melting things and messing with chemicals...and probably burn the garage down. In the meantime, thanks for another wonderful two-parter!
Sreetips, I gotta admit... of all your techniques for gold precipitation, the SO2 gas method is my personal favorite. Idk if it's the delay of the reaction mounting the anticipation, or the assurance that it doesn't precipitate PGM's, or even the cool way it's setup ( a little complex but still simple and fun looking )... probably all 3😆
Man...I'll tell you what, sir! Life is good. I'm cutting up my NY Strip roast into 1" steaks and watching you go this route with precipitating the gold in this manner. I've seen you do this another time and was fascinated with the process and the outcome. It's almost as cool as getting silver from sugar 😂. Not sure if you'll ever beat that trick😅 IMHO 😊 However, another great video! Im sure you and the Mrs. Had a great day at the sales. Eager to see your good buys. Thanks for taking the time left of your busy day to share this magnificent step in refining God's gold.
Long time scrapper but still new to gold recovery and refining said gold. But from what ive learned on youtube university is that using different precipitants for the drops really gives the purest gold.
A tiny, even microscopic piece of gold precipitates and clings to an imperfection on the inside of the glass beaker. Soon, it and others grow in all of the imperfections showing all of the minute scratches on the inside of the glass. The fuzzy lines of gold crystals marking the scratches. I think it is both neat and gorgeous. Once again, Sr. I watched every moment. Thank you and the Mrs. for sharing the love of your hobbies with us.
SO2 reaction is the best. I was thinking during Pt1 episode, "it's been a while since we've seen a SO2 precipitation" and here it is. Never disappoints.
Sreetips reminds me of my high school physics teacher, Mr Willis. Very matter of fadt with a little tinge of humor. Awesome video as always. Love this content.
I've been watching this channel for 7 years now I can't believe how beautiful the gold looks after it's melted even the precipitated gold looks awesome
7:56 scared the heck out of me with that hose. I had just turned off the lights to watch yt before bed after watching a horror movie and that hose scared the heck out of me as i was faced towards the wall
This would be cool to see with the slow motion high resolution the slo mo guys filming the gold appearing out of no where in the gas/gold liquid scene at around 17:40
Another New Zealander watching your videos. Got plenty of chemistry expertise with cyanidation of gold (got that in Johannesburg, South Africa). Working with acid is very different. Got all my current expertise from you. Thank you!
Sreetips should be a teacher on PBS or something like that. Your passion transpires in your videos. It’s well explained and keeps improving with each videos. I will never get bored watching it. 🇨🇦✌🏻👍🏻
What percentage of impurities do the plastics and other vessels enter into to the equation? I know that distilled water is supposed to be pure - but there are absolutely other products introduced from all the bottles and beakers and such...
Always amazed at the brightness of the high purity solution. At about the 12 minute mark the light passing through it and playing out on the back wall of the fume hood looks like golden fire. And that pocket watch is a trooper! The belt clip is not long for this world, but the watch is almost unaffected.
SO2 gas is one of my favorite precipitations you do, but the oxalic acid is by far the best to watch and when you’ve poured bars right after and they have the blue flecks just like the silver chloride bars ! Awesome content as always thank you sir !
How long could you actually store gold in solution? Months? Years? Second part of question, would the solution evaporate? And if so would the gold just stay behind? Thanks love your channel
Gold in solution will keep indefinitely. Evaporate to dryness leave burnt-orange chloroauric acid crystals. They too should last indefinitely. To get metallic gold just re-hydrate with some hot HCl, filter, drop the gold with SMB. The gold chloride crystals can’t be detected with a metal detector because it’s a salt, not metallic.
When the SO2 gas roils in reaction, for the first time I could envision how gold deposits could form deep within the earth -- under perfect conditions -- in a fissure of ancient baby igneous rock. Pressure bake for a couple million years, add uplift and erosion, and some lucky prospector pans a nugget out of a mountain stream. Amazing.👍
@@hansweichselbaum2534, an alloy is a mixture of two or more metals. When he inquarted in part 1 he created an alloy of roughly 25% gold and 75% silver (mostly) and a little copper. So, no.
@@CuttinEJ I know, this was already highly purified gold which he had precipitated before. Either it was too little HCl, because he had certainly an excess of H2O2, or it was some kind of surface passivation. Or it was a kind of mixture of gold with some contaminant. That's why I used the term 'alloy'.
@@hansweichselbaum2534, after the first dissolution he still had a considerable amount of elemental gold that was undissolved. He restarted the digestion with fresh chemicals. But notice the amount of HCl. It’s not very much. And though the gold dissolves rather quickly at first, it also fairly quickly reaches a point where no more Peroxide has any effect. Only 3 things cause a reaction to stop. Either you run out of metal, or you run out of the solvent (Peroxide, Nitric, etc…) or your medium becomes saturated. We can see that gold still remains, we saw that several additions of solvent had no effect so the only factor left is the medium into which the gold is to be dissolved. I will say that I do believe that all of the Peroxide was consumed, but that’s because of the way Peroxide reacts with almost everything. What I would like to see sometime, is when he reaches this point, add 100 ml of HCl and then a little more Peroxide and see what happens. Note: This being the 3rd time through the process, I highly doubt there’s any detectable contaminant.
This gas precipitation is my favorite. I also think disolving with 29% hydrogen peroxide makes the gold even shinier. Can't wait for the 3rd installment
I have a project. I have aquired a lot of electronics. I was wondering if you could/would do a video on processing a lot of circuit boards using only products that can be bought locally? I have HLC and about three gallons of 32% H2O2. My wife if getting tired of my "junk pile"
Thanks for sharing your hobby with us. I'm going to start investing in probably some bullion and will probably never refine anything but I love seeing your process
Gold and silver are not investments, they are real money. When you buy gold, it’s not an expense. You’re actually converting paper, that’s declining in value, into metals (gold and silver), that are rising in value.
S02 gas monitor is what we all have to wear in the oil feilds. If you smell rotton eggs your probably dead already it is that fast. Sreetip man you allways impress me. Your a brilliant man 😂
I don't know for sure but I would hazard a guess that the peroxide is reacting away without coming into contact with the last bit of gold based on the large volume of the beaker compared with the small amount of gold. I would try with a tall form beaker or a round bottom or pear bottom flask with minimum amount of hydrochloric so you're guaranteed the H2O2 comes into contact with gold powder.
Your pear shaped separating funnel would be the ideal shape but heating it will be a problem. A measuring cylinder would be great too and easier to heat.
I love the diversity of refining methods shown! 😀 The hydrogen peroxide method seems a little fiddly in that not all the gold goes into solution. You mentioned this a common occurrence. Is there an advantage to using the hydrogen peroxide method versus the others? Some of the commenters mentioned ways to adjust the process to get the hydrogen peroxide method to successfully get all of the gold into solution. Will you consider a future video experimenting with the process to try and get everything into solution?
Good evening! I don't remember if you retired as a Chief or Master Chief. Could you refresh me on that, please? Also, are there more elaborate ways to refine gold? I love the SO2 refining method.
Hello Sreetips good to see you. Thanks for uploading the fun videos . I have a question that came to me , when the gold is in solution does it still set off a metal detector? 😢
No, it’s a metal chloride in solution. Think of table salt. It’s a compound of chlorine gas and sodium metal. I’m pretty sure sodium metal will set off a metal detector. But sodium chloride (table salt) won’t.
@@sreetips , Ohh Wow that's right ! I hadn't thought about that! Thanks for the education, Mr. Sreetips you're very kind. I appreciate you taking the time to answer my question in depth.
Have you tried using a micro bubbler with this gas method? I assume smaller bubbles would give better gas absorption into the solution and speed up the reaction.
What is that glassware called which you use for adding the sulfuric acid? I should know, but my chemistry study was half a century ago, and in German. Thanks!
Regarding that last bit of gold that wouldn't dissolve, would it have been the worst thing in the world to just add that to the results of the final precipitation? Basically it would mean that that tiny, little bit of gold was only dissolved/precipitated twice instead 3 times. But it was pretty darn pure after the 2nd precipitation and it's such a small amount I'd imagine any negative effect would be negligible, no?
So, the infamous waste container. When you get a bunch of acids etc built up, how do you dispose of it? Acid+base = salt+water+other stuff? Send it off as a batch of junk? Keep it as dirty aqua regia?
Oh yeah, nice, we’re getting the full range of dissolution and precipitation. Breaking out the H₂O₂ and the SO₂ rather than just the boring Aqua Regia and SMB.
Hello Sir how are you? As you know hydrogen peroxide is an oxidiser, but is one with both the positive and negative ions. Hence it is very much possible for it to escape a hot solution before it has a proper chance to react with the material beneath. From my observation, with the intial drops of H202, the solution dissolves the sediment as it is only getting warmer to mild hot. Because h202, has positive ions that collide with the negative chloride ions realeasing them as a gas, therefore your HCL may also be losing its strength. Hence the dissolution loses it dissolving rate after the 1hour15min mark. You can double check the acidity of solution with a pH paper
Are you sure those last bits that won't go into solution are gold? You intentionally precipitate lead for instance. Granted this was second or third refining but maybe it came along?
so does doing the peroxide reaction and the gaseous precipitation make better purity of gold? if so how? or are these just different ways to achieve the same result?
@sreetips Id like to thank you for all the content you put out. Today I refined my first gold piece, the yield was as expected. A large part of what I was able to do was because of you. Thank you for all the effor you put into creating these videos and your continuous guidance.. Thanks a lot... :)
as to your question earlier about why the last bit of gold didnt dissolve: in your last video, when you were talking about boiling and rinsing until there is no color left in the solution, and how not doing it enough was a "rookie mistake", there was a little bit of blue left in the solution in the last boil/rinse portion. could that be why that last bit didnt dissolve? *i want to be clear... i am in no way insinuating that youre a "rookie". i was just quoting your comment. great work on your videos!
Because gas is so much cleaner. Adding SMB puts a bunch of salts in with the gold that must be rinsed off. The the pure clean gas, no salts, no rinsing.
Aren't you dripping HCL into the SMB? Then, the gas bubbles into the H2SO4, which then bubbles into the solution? I don't want to blow myself up when I try this. Incase you were wondering why I'm asking so many questions.
The gold sponge. If you didn't do this step, using HCL and H2O2, to dissolve the sponge this final time, would the sponge not be close to 99.9% Fine? I'm curious as I haven't done this step before. What I have, so far, passed the 22K acid test.
In my country i can't buy either nitric acid, nitrate to make acid or concentrated hydrogen peroxide, but i could try to concentrate hydrogen peroxide from 12%
@@sreetips High end: Iron 10PPM, calcium 170 MG/l you used about a l of water ice in the process, perhaps 1.5l. So 1000g of H2O (S)= .001g Fe , .17g of Ca Mg and others, so we could see the. Ca contamination if you had hard water, and that tiny black speck, could have been iron. Next time see if it is attracted to a magnetic field.
Refresh my memory - Isn't SO2 roughly equal to "You start choking on the overwhelming stench of rotten eggs, then you fall over, the coroner declares you dead, and things proceed from there"? Or is that H2S? I know neither one is "happy gas", but I always forget which one is the "ultra-nasty" of the pair.

A/P dissolve excludes nitric, gas precip exclude reagent being added directly.

Because gas is so much cleaner. Adding SMB puts a bunch of salts in with the gold that must be rinsed off. The the pure clean gas, no salts, no rinsing.
Aren't you dripping HCL into the SMB? Then, the gas bubbles into the H2SO4, which then bubbles into the solution? I don't want to blow myself up when I try this. Incase you were wondering why I'm asking so many questions.
I drip sulfuric, not HCl.
Stir bar partyyyy
Id love to see this reaction happen with a stir bar vortex going at the same time...🤔
Sreetips, is there an alternative to generate SO2 besides sulfuric acid, and SMB. In case these chemicals are not available. Thanks in advance.
I think burning sulfur emits SO2 gas. But that would probably ruin the gas generator.
@@sreetips Thanks for the feedback, and thank you for the great channel!
Niceeeee… now that’s fun.
Already done downloading both parts for offline watching
The gold sponge. If you didn't do this step, using HCL and H2O2, to dissolve the sponge this final time, would the sponge not be close to 99.9% Fine? I'm curious as I haven't done this step before. What I have, so far, passed the 22K acid test.
I don’t know. I sent some in and it came back three nines.

By the way...now come the spring in Norway 🙂🌺🌺
After a long cold winter, spring is a welcome sight.
@@sreetips Wonderful Sreetips 🌸🔥🙂
Wooo first🎉🎉🎉
In my country i can't buy either nitric acid, nitrate to make acid or concentrated hydrogen peroxide, but i could try to concentrate hydrogen peroxide from 12%

Not that I know of.

I need to get a presure equalizing funnal
No vapor lock! They aren’t that expensive. Mine is 250ml capacity.
Are you using distilled water for your ice cubes?
Tap water
@@sreetips That could be the contamination sourse in your process.
Parts per million
@@sreetips High end: Iron 10PPM, calcium 170 MG/l you used about a l of water ice in the process, perhaps 1.5l. So 1000g of H2O (S)= .001g Fe , .17g of Ca Mg and others, so we could see the. Ca contamination if you had hard water, and that tiny black speck, could have been iron. Next time see if it is attracted to a magnetic field.
Industry standard for pure gold is 999 parts per thousand. Trace contamination in tap water is not enough to report in a precious metals assay.

Refresh my memory - Isn't SO2 roughly equal to "You start choking on the overwhelming stench of rotten eggs, then you fall over, the coroner declares you dead, and things proceed from there"? Or is that H2S? I know neither one is "happy gas", but I always forget which one is the "ultra-nasty" of the pair.
Hydrogen sulfide is rotten eggs smell (I think). SO2 gas is what you get from burning sulfur. It will gag you and put a hurt on your lungs.
SO2 reacts with moisture ( in your lungs) to reform sulphuric acid.
