Gold Recovery & Refining with Hydrogen Peroxide, Easier Gold Smelting

We are trying to find a fast, safe, and efficient way to recover more gold and oxidize the sulfides in our ore. Hydrogen peroxide is a strong oxidizer and in this experiment we try to use concentrated H2O2 to oxidize our sulfides and liberate ore gold for recovery and later refining. The experiment didn't go exactly as planned, but it did answer some questions for us on a better refining and gold smelting method.

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 😉

[@TheGayestPersononYouTube]

Just as a tip if you do this with peroxide in the future, some oxides (namely manganese dioxide) will catalytically break down the peroxide so you may never get it to stop fizzing depending on the sample. Also, adding HCl to the peroxide might start dissolving the free gold into solution as the H2O2 is strong enough to oxidize the gold for the HCl to dissolve like nitric acid is in aqua regia. Love your channel, man!

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.

[@mwilson14]

The H2O2 is mostly decomposing via catalytic in that process. It is best to roast with potassium nitrate.

[@mikeconnery4652]

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.

[@B0NGSHEAD]

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.

[@GSProspecting]

Great work fam. Cool indeed. Gold squad out!!!

[@anthonymarcocasamsssima8998]

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.

Love your videos . It's like I'm sitting in a mining class.

[@idontknowmyfirstname69]

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

[@idontknowmyfirstname69]

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

[@pafischer]

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.

[@benderrodriguez142]

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.

[@joshp6061]

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

[@mehurtmyfinger]

Gday mate. You probably dissolved some gold into the H2O2. Add a piece of copper into the H2O2, and see if any black metal cements onto it, to recover any that has been dissolved

[@beckttbeck8450]

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.

[@briancummings1206]

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?

[@blu12gaming44]

Try using Sodium Percarbonate (aka Solid Hydrogen Peroxide) to see if it's more efficient than 35% Hydrogen Peroxide.

[@r0cketplumber]

I'm pretty sure even well-reacted metal oxides will still catalyze peroxide, just a bit less than the sulfides. I know from personal experience that 90% peroxide is much more enthusiastic in its reactions and once mixed with pain old dirt, keeps going until the concentration is very low, particularly when hot. To get a more accurate check of the sample mass, I think you should have boiled away the used peroxide that carried away some fines, and added them back into the sample. That probably would have brought it back up close to 50 grams.

[@johnnysilverado3234]

I don’t know of any reactions that would take place without a acid(base) catalyst of some type. I am glad that you have some respect for the 35% peroxide. It’s got almost enough energy in it to turn all the water to steam in an instant and increase in volume 12000x. You can build yourself a jetpack and run it with what you have left.
