When dealing with hydrogen sulphide gas, there are a couple of factors 1. Use a fume hood. This stuff is no joke 2. If you stop smelling the H2S, RUN!!! H2S in higher concentrations will shut down your ability to detect it. I grew up near a heavy water plant 😉
Thank you Sir . 23 years ago my Daughter and I camped in Montaana pre Grizz . We found gold pandemic recently returned there and am exploring the source . I spent 5 weeks this past summer 20 MI in dodging Grizz and tons of Moose . So it's back at it after melt off . I appreciate that I am a fit 71 year guy . Cheers.
From a chemistry perspective: Add some water to your sample so you can stir (as quickly as possible) while slowly adding the peroxide (H2O2) to it. Most likely some manganese (or similar) acting as a catalyst to decompose the peroxide to oxygen and water (2 H2O2 ---> 2 H2O + O2). Most of the oxygen that is released (~165 grams from a liter of 35% hydrogen peroxide) is just being released into the air. By stiring your sample and adding the peroxide slowly, you will get a far more efficient reaction.
Great video. First put the 50 grams into a jar, then add 4 parts muratic acid to 1 part nitric acid. This fluid should be heated past 150* f for a few minutes You should get a bright yellow fluid. Add pure water and drain the fluid only out.
Refining with Sodium Bisulphate It was considered that the silver as well as the base metals might be removed by some preliminary treatment. Nitric acid was ineffective on the retorted gold tried; sulphuric acid had little effect, but on testing with bisulphate of sodium it was found that base metals were removed or oxidised, and that silver sulphate formed The retorted gold was heated in porcelain or dense fireclay pots to a dull red heat for some time, generally as long as sulphur dioxide was evolved. The fused pyrosulphate was then poured out, and the cake drained as completely as possible. These were afterwards washed with hot water until the silver sulphate had been removed. The cake of melted pyrosulphate was also dissolved, and the silver present in the solution precipitated on iron, or by other well-known means. The gold could now be smelted, and invariably would be found to be much purer than when smelted by older methods. The silver and base metals were also removed at a fraction of the cost required by the chlorine method. The results obtained, however, were variable; one sample would be purified from about 80 to 96 per cent., yet another would only be increased by five or six per cent. The cause of this variation seemed to be that when coarse gold is amalgamated the mercury only affects the outer crust, so that on retorting there would be left pieces of gold porous on the outside, but unaltered within. In order to determine whether the gold and silver, if amalgamated in a fine state of division and then retorted would part, 80 grains of gold and 20 grains of silver were taken and amalgamated. The amalgam was retorted, and the resulting gold was of pale yellow colour. This was treated by boiling with strong sulphuric acid, which removed part of the silver; it was afterwards treated by fusion with sodium bisulphate, which removed more. The gold remaining was then washed with water, and after the silver sulphate had been removed the metal was weighed and parted. It was found to consist of: Gold, 97.2; silver, 2.8. It is, therefore, a difficult matter to remove the whole of the silver, even when finely divided originally by this treatment: It might be stated here, although detailed reference will be made to it later on, that by using phosphoric acid with sulphate of sodium as a solvent that the retorted gold made in the same way was raised to: 99.2 gold. 0.8 silver.
I tried this a while ago. You need to add 90% acetic acid to break the oxide layer you built on the surface of the sulfides. The reaction will continue over and over till nothing is left to oxidize. The reaction is a exothermic one that boils over, the bubbles cool it and it reheats as the next layer oxidizes. This is paracetic acid. Acetic and hydrogen peroxide. You can add salt to it as well.
I watch tons of gold mining, recovery, and reviews. So to be added at this point is tough because I want my feeds to have more than just gold recovery videos. However, what it takes to get added is good solid information and techniques. And you deliver both. And doing a failing experiment is one of them. I'm sure a lot of prospectors try these tricks and you've proven that it might not be worth the trouble. I don't know, I was impressed with the video and procedures used, and comparison techniques. So for those reasons I have no other choice but to add you to the subscriptions. Well done. I look forward to more.
@@scrappydoo7887 The point I was talking about is the level H2S you're exposed to. They don't make acid gas & organic vapor respirator filters that specifically filter hydrogen sulfide for no reason... Mike brown is wrong in saying they don't protect against H2S gas, because they do.
Adding HCl with the peroxide will dissolve the gold as well. Might be useful to make a concentrate of gold chloride solution and leave all the silicates behind.
You need morw than Hcl And Peroxide, you need heat, a lot plus stirring AND a vast amount of Peroxide. The ratio can be 1:5 when all said and done. Its cheaper to just use nitric acid since you can dissolve 4 troy ounces in 300ml HCL plus 15ml Nitric
Dean here. I am a pourer of SM's and as I do torch work on friends plaser I am thinking this may be my salvation for all that come to me with bits and pieces of their hard worked for beautise they worked so hard for. Thankx bud. Drug store peroxide is plenty and easy on the wallet eh. later on I see that more needs to go into this project but anything is better than quicksilver eh !
really good experiment Jason.....great explanation of the process ....love how you are pushing the envelope...we smashed that like button and we are Subscribed and hit the Bell icon so we don't miss anything ...... good job sonny Jim.
Hate to tell you, but if you had added HCL to the h2o2 (Hydrogen Peroxide) it will create a weak version of aqua regia, and start dissolving the gold and other precious metals... and basically, not a good plan. If you add an air hose into the crucible with just atmospheric air being pumped in, it will during the smelt oxidize all the sulfides, and you can actually turn the gas off in the furnace and it will continue to heat, as the air and sulfides combust... crazy stuff, I know, but a huge bit of fun to watch .
could you pump oxygen down there? using a tiny medical tank/regulator, a bubbler to prevent blowback then down threw a high pressure stainless steel braided hose.? I happen to have these random items, But I am under strict rules not to blow the house up with my projects. lol , thank you!!
@@garrisonkoby3448 atmospheric air is absolutely preferable, pure O2 in this case would be an extreme option, and blowing up your house might not happen, however, the smelt would in all likelihood super heat, at least into the 3000 degrees F... Using braided stainless, is good, the idea is to not and consumable metals to the smelt... stainless, is a great choice. I use atmospheric air from a 35 lb air compressor, and a regulator value to add the air...
Very nice experiment, thank you for sharing! There's lots of gold (panning) channels on TH-cam and I always wonder how much gold theh throw out in their sulfides. I'd love to see more experiments like this!
Yeah it really seems like some mineral is catalytically breaking down the H2O2. I'm betting most of your peroxide is getting wasted before it gets to react with the sulfides unfortunately. Very cool experiment though!
Just started watching your videos over the past few days and I’m hooked. Love watching pure research 🧐 being performed through commonsensical researchers outside of the constraints of the learned indoctrinated system. Love it!!
Like the video, a good control experiment would to pan down a pan full of sample. Recover as much gold as possible. Then that same sample dry and put peroxide on it like you did, however if there’s gold it works if there is no more gold than you could identify that was left when you panned it down the 1st time it didn’t work. Great video appreciate the work you put into it. Awesome
If you add water before the peroxide it will allow you to use less. Going with the straight 35% peroxide a lot is getting wasted to thermal decomp as opposed to oxidizing the sulfur compounds. Or do it with the gold pan in an ice bath to slow manage the heat.
My crazy idea is to float out the fines in the foam like they do floating platinum ore. I have always heard that if you get any oil. your fines will float away. not the 100 fines--the 200 fines and even smaller. Aussie Bloke Prospecting uses a vibrator and slows his sluice and the angle is 11 inches of run to 1 inch of rise. It may be that a heavily conditioned shampoo or just conditioner? who knows. Keep up the good work. And Thank you.
What's going on there is a decomposition reaction. The sulfides and sulfates do oxidize, but mainly they trigger an energetic decomposition of the peroxide into water and ionic oxygen. So the released gasses are a combination of water vapor, molecular oxygen, and sulphur dioxide. Its not much but i still would do something like this under ventilation. Honestly you're lucky your sulfates and sulfide concentrations are low. That strong of peroxide mixed with pure sulphur salts will violently decompose, think of a hot steam explosion in your face, along with the gasses taking very hot peroxide with it. One thing worse than strong peroxide... Is hot strong peroxide... A lot worse. I love your videos man keep making em... Its my dream kinda work but where i live i have to do my mining from ewaste, since ohio is lacking in gold deposits. Be safe
Also dont have hot peroxide around gold. That strong doesnt need to get very hot to oxidize the finer pieces of gold. Might be good if you do this to save your liquid waste and test with stannous chloride to be sure you didn't inadvertently put some of your gold into solution
Strong Peroxide and HCl mixed together will dissolve the gold as well as oxidize the sulfides. It will certainly dissolve copper. If you mix these chemicals together, don't discard the fluid afterwards, it will have gold in it!
@@budzag Look up a youtuber named Sreetips - he specializes in refining scrap gold and silver. But his methods would also be good for extracting pure gold and pure silver from the buttons that come from the cupel. If it hasn't already been done I'd love to see a collab with him and Jason to see how much 24K can be extracted from a couple of buttons from Jason's mine. Or a collab with him and Dan Hurd ..
Hydrogen peroxide also oxidizes iron, it’s a big contributor to stainless steel rust. It’s possible you were just eating away at the gold pan itself. I would use a plastic or glass vessel to perform the reaction next time. Also the smoke your were getting was probably just steam from the peroxide boiling from the heat of the reaction. You could probably use half as much and get the same result from adding smaller portions at a time
I knew a guy that knew con artist stuff. He used to keep a big jar 1/3 full of acid. He'd throw bits of discarded computer chips, etc, in there because it "got the gold out".
Knowledge and perseverance is key to success and you have both. You lab methods are both scientific and intresting. How ever i dont think you determined recovered gold content of each sample. More refined steps could get you the answer if you hadnt mixed the slag?
Your gold there is likely superfine powder that was stripped physically from the ore by the peroxide getting underneath and decomposing, popping it off. Which means it's good to see it, but the yield ultimately would have been similar anyways. You must have a little manganese in your ore, that H2O2 catalyzed extremely quickly... but that also means it all decomposed without doing much chemically.
Peroxide violently reacts and breaks down with silver and some other metals. I'm not sure this process is wise. But that being said every experiment is a learning opportunity
I’m sure it’s been said but the bubbling reaction will never stop and one treatment will probably do it. The oxygen from the peroxide is released by iron oxide catalytically
hey the thing you should mention is that the process takes a little time, the longer it soaks the more it dissolves into the peroxide.... then if you bubble so2 gas into the gold peroxide solution or boil the peroxide off then wash it it will re solidify the gold into a powder. oh and that peroxide is very strong I don't know if you need it 35 percent i have seen sreetips on you tube do it with 3 percent and i have also. It takes longer though.
Using 35% you can start fire if its get on wood and leather at 35% but after it reach reaction and stops if left it turn into water. Used thousands of gallons weekly in making catalyst for oil and other uses.
Have you thought about putting the sulfide laden gold in a dry, O2 rich environment? Would it even work? I'm thinking you can put it in a glass vessel with one gas input and one gas output. The output would need a water trap to keep the O2 in the vessel. Then you could use a solar panel to generate some DC current and use the current to split distilled water into hydrogen and oxygen. Vent the oxygen into the vessel and vent the hydrogen into the atmosphere. The oxygen would build up in the vessel and hopefully react with the sulfides. You could try it first with some bottled oxygen to see if it causes a chemical reaction with the sulfides.
I use at least 12.5% in my gold sand and black sand and crushed ore but I roast it all first and let it cool down and the fry the hell out of all my material but I let it sit in peroxide for at least five hours. I get a better yield by at least 25% by doing it this way.
The sulfides oxidise to elemental sulfur and sulfates dropping the gold as they do. Nitric acid + hydrogen peroxide might be a better combination but may dissolve gold which then recements out as the potential drops
You can buy H2O2 from hair salons or hair salon supply stores at 40% & 50% by volume and it’s cheaper but be sure to get the liquid not the cream. I use it for bleaching skulls for European mounts.
Hydrochloric and peroxide will put it into solution as Gold chloride that said I would suggest you try that because I don't know about the soft lights but that peroxide kind of expensive to be going through it as fast as you are on a meager 50 g which doesn't seem to be that cost-effective
I'm not sure but on the side of caution I would not let that vapor get on your skin it could do some irritation. I would stand up wind all the reaction is happening. Also want another point we were cleaning grease off the concrete floors of an old shop once and poured muriatic acid on the concrete to eat the grease out where they used to work on tractors in the vapors arrested anything that had iron content and wasn't painted anywhere it was located in the shop. Might be something you might want to try on this if you haven't already. The only thing I know for sure is you don't mix bleach with hydrogen peroxide because it immediately gives off sulfuric acid gas and you had to leave immediately.
Vapor is just oxygen and water. "The only thing I know for sure is you don't mix bleach with hydrogen peroxide because it immediately gives off sulfuric acid gas" And where does the sulfur comes from? NaClO + H2O2 I see no S anywhere
think i would have used the pan to extract the gold from the sample. then snuffed the gold up. then i would have then used the peroxide on what was left. any gold after that would prove that the peroxide works or not. might be worth running a 100grm sample
Might be interesting to see if sprinkling the matrix into the solution vs pouring the solution into the matrix would use less of the solution, or perhaps remove more of the sulfates?
@@hondosmith3172 doesn't work like that. Any strong oxodizer mixed with hcl will disolve gold. You can even disolve gold using nitrate salts like potasium nitrate or sodium nitrate ect... mixed with hcl.

The H2O2 is mostly decomposing via catalytic in that process. It is best to roast with potassium nitrate.
Use jet dry, you have gold suspended in/on the water, helps break the surface tension to let it fall to the bottom.
Safety tip, a filtered mask does not protect against H2S gas. The only protection from H2S is a supplied air respirator.
Respirator does to a point

Great work fam. Cool indeed. Gold squad out!!!
Much of the 'smoke' is steam BTW. H2O2 is what the original rocket pack used. Over a platinum catalyst I believe.
There is likely plenty of hydrogen sulfide which would be a side product of the reaction.
It was silver and peroxide for rockets
Can the H202 be recovered from tne steam to be used as fuel for my car? I have a hydrogen unit installed now.

HCL plus peroxide is useful for a later step in the refining process - the peroxide has the same oxidizing effect as nitric does in aqua regia.
Strong Peroxide and HCl mixed together will dissolve the gold as well as oxidize the sulfides. It will certainly dissolve copper. If you mix these chemicals together, don't discard the fluid afterwards, it will have gold in it!
Could you then just let the liquid evaporate out and smelt every thing left behind?

hey the thing you should mention is that the process takes a little time, the longer it soaks the more it dissolves into the peroxide.... then if you bubble so2 gas into the gold peroxide solution or boil the peroxide off then wash it it will re solidify the gold into a powder. oh and that peroxide is very strong I don't know if you need it 35 percent i have seen sreetips on you tube do it with 3 percent and i have also. It takes longer though.
Jason, as always awesome videos. Very informative! I wish I could join you in your experiments and learn what you know!!
Very cool experiment. Great video!
Some of the black sand is fe04....black iron oxide. Heating before peroxide would likely make more red n brown w less black left.
Really cool work.
Thank you 👍
Thank you! Cheers!
interesting,,,,,,i will try this,,,,,,,,,thank you for the information,,,,,
Bagus dan sangat membantu para penambang yang baru belajar.
Cool awesome, greetings from Aruba🌴
There must be a lot of germs in that sand with all that fizzing!
I can feel the stinging from here.
GOOD JOB, thanks again for educating me
Using 35% you can start fire if its get on wood and leather at 35% but after it reach reaction and stops if left it turn into water. Used thousands of gallons weekly in making catalyst for oil and other uses.
Have you thought about putting the sulfide laden gold in a dry, O2 rich environment? Would it even work? I'm thinking you can put it in a glass vessel with one gas input and one gas output. The output would need a water trap to keep the O2 in the vessel. Then you could use a solar panel to generate some DC current and use the current to split distilled water into hydrogen and oxygen. Vent the oxygen into the vessel and vent the hydrogen into the atmosphere. The oxygen would build up in the vessel and hopefully react with the sulfides. You could try it first with some bottled oxygen to see if it causes a chemical reaction with the sulfides.
I use at least 12.5% in my gold sand and black sand and crushed ore but I roast it all first and let it cool down and the fry the hell out of all my material but I let it sit in peroxide for at least five hours. I get a better yield by at least 25% by doing it this way.
holy crap, that's a hell of a reaction
The sulfides oxidise to elemental sulfur and sulfates dropping the gold as they do. Nitric acid + hydrogen peroxide might be a better combination but may dissolve gold which then recements out as the potential drops
Just capture and recirculate man! Don’t wast that! Encapsulate and circulation with a bladder for expansion you can do it!
You can buy H2O2 from hair salons or hair salon supply stores at 40% & 50% by volume and it’s cheaper but be sure to get the liquid not the cream. I use it for bleaching skulls for European mounts.
Great stuff, thank you for trying & for sharing.
Nice and informative thank you two thumbs
Thank you for smashing rocks so I don’t have to. You’re a real timesaver.
Really good experiment. I seem to learn something new on every video.😎⛏⛏🔥🔥
Great video, thank you Jason!
Hydrochloric and peroxide will put it into solution as Gold chloride that said I would suggest you try that because I don't know about the soft lights but that peroxide kind of expensive to be going through it as fast as you are on a meager 50 g which doesn't seem to be that cost-effective
Excellent video as always thank you 😊 🙏 👍
I'm not sure but on the side of caution I would not let that vapor get on your skin it could do some irritation. I would stand up wind all the reaction is happening.
Also want another point we were cleaning grease off the concrete floors of an old shop once and poured muriatic acid on the concrete to eat the grease out where they used to work on tractors in the vapors arrested anything that had iron content and wasn't painted anywhere it was located in the shop. Might be something you might want to try on this if you haven't already.
The only thing I know for sure is you don't mix bleach with hydrogen peroxide because it immediately gives off sulfuric acid gas and you had to leave immediately.
Vapor is just oxygen and water.
"The only thing I know for sure is you don't mix bleach with hydrogen peroxide because it immediately gives off sulfuric acid gas"
And where does the sulfur comes from?
NaClO
+
H2O2
I see no S anywhere
think i would have used the pan to extract the gold from the sample. then snuffed the gold up. then i would have then used the peroxide on what was left. any gold after that would prove that the peroxide works or not. might be worth running a 100grm sample
Very informative, thank you! Saved for future reference.
hello friend i really like your way of working i hope we can be friends greetings from me traditional indonesian gold miner👍☕️🔔👈🇮🇩🙏🏻🤝
interesting experiment :) well explained :) great information :)
Might be interesting to see if sprinkling the matrix into the solution vs pouring the solution into the matrix would use less of the solution, or perhaps remove more of the sulfates?
Great info and vid.. always wondered about that now I know!
I would precipitate the decanted fluid ,or just evaporate it down to recover gold values.
Super interesting brother 👍
What about roasting and then using a bit of h202 to really top off the process? Just 1 cycle of h202 will oxidize alot of un roasted sulfides
If you add Hcl and the H2O2 you will disolve gold likely
It's HCl and HNO3, mixed together that creates Aqua Regia which is capable of dissolving gold
Yep it will definitely dissolve any gold cause when you mix those you basically have (Aqua Regina)
Not without nitric acid
@@hondosmith3172 doesn't work like that. Any strong oxodizer mixed with hcl will disolve gold. You can even disolve gold using nitrate salts like potasium nitrate or sodium nitrate ect... mixed with hcl.
@@walkthroughguru cool, I really am just beginning to learn this stuff
