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.

Thanks a bunch for these refining videos without complex chemicals. Can't tell you how much that helps my operation capabilities.

Not sure how I didn’t find this channel before but I love it! It’s like watching my kids do a STEM project but with gold!

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.

Thankyou Jason. I learned so much. I’ll watch it a few more times with notes. You are incredible.

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.

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!

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 😉

Another very informative video Jason. Thanks for taking the time showing us these processes.

Very nice experiment, thank you for sharing! There's lots of gold (panning) channels on KZfaq and I always wonder how much gold theh throw out in their sulfides. I'd love to see more experiments like this!

Love your videos Jason. You cut right through it and come up with the goods every time, and explain it really well.

Jason, as always awesome videos. Very informative! I wish I could join you in your experiments and learn what you know!!

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

This was fun to watch! Thanks for the tips!

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.

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.

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

Dang!! You sure are a smart one.. need more people like you in this world.. love watching your videos.. 😊 stay safe, happy, n healthy. 👍

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.

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

Safety tip, a filtered mask does not protect against H2S gas. The only protection from H2S is a supplied air respirator.

Watching this and a notification came up for a new one 💪😏 keepem comin ..love the content

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.

Awesome education brother thank you for doing and sharing unsuccessful melts too I have learned a lot from binge watching your videos 😂

Thank you Jason... from Jason.. (Jorojin Nomad) .... love your work and experiments..

Thanks for your time Jason it was a great video

Use jet dry, you have gold suspended in/on the water, helps break the surface tension to let it fall to the bottom.

You know your chemistry man !!

Thanks for your time Jason it was a great video 👍😊

Best Channel in Gold Exploration My greetings to you 👍

I like these experiments, nice !

Very cool experiment. Great video!

Very informative, thank you! Saved for future reference.

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 !

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 .

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.

Great experiment !

Great info and vid.. always wondered about that now I know!

My favorite gold recovery videos.👍

Great video! Found the mat explanation very helpful.

I’m really glad you found H202. God bless

Fantastic your videos, I have a question, would it be interesting to burn the ore before soaking it in H2O2?

Thank you, I really enjoyed this video. It would be interesting to see a video including a solution of H2O2 + HCL.

Well done and informative as well.✌️

Great stuff, thank you for trying & for sharing.

Keep BLAZING a trail, exellent info, thanks

Great video, thank you Jason!

The balance of the weight is probably dissolved in the liquid that you decanted.

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

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

Really good experiment. I seem to learn something new on every video.😎⛏⛏🔥🔥

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!!

Excellent video as always thank you 😊 🙏 👍

Hey man I live in concrete just east of you and I appreciate this video big time man help me out a lot in my situation

GOOD JOB, thanks again for educating me

Really cool work. Thank you 👍

Very informative!

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.

Amazing information, thanks for sharing.

Great informative video Jason. Thanks

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

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.

Nice and informative thank you two thumbs

interesting experiment :) well explained :) great information :)

Great Video!

Much of the 'smoke' is steam BTW. H2O2 is what the original rocket pack used. Over a platinum catalyst I believe.

Cool awesome, greetings from Aruba🌴

Surprised it didn’t melt the pan. Good experiment.

Great experiment

Enjoyed watching your video.🙂

Very interesting a guy on KZfaq named streetips does alot of refining gold and precious metals. Thanks for sharing! I subscribed

Super video and info. Tjanks

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.

Nice work and great explanation of the process. Thanks Jason ✌️PT

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!

holy crap, that's a hell of a reaction

Super interesting brother 👍

Thank you God bless you

I think most of the boiling was just decomposition of the hydrogen peroxide into water and oxygen. Finely divided materials, especially metals, will catalyze violent decomposition of H2O2. You might have better luck adding a solid oxidizer such as potassium nitrate to your sulfides and igniting the mix.

It would be interesting though to see iron smelting with and without h2o2

Would have been interesting to see a 100g roasted sample as a control.

Good experiment. Would have been cool to have 3 samples, no treatment, hydrogen peroxide treatment, and roast. Would also love to see a leach with sodium cyanide. Not sure if that is possible or not?

Good experiment.

Reminds me of the wicked witch melting. I was wondering if you would melt your pan. Neat.

Great video. What happens if you have platinum or other precious metal in there would it be in the gold or would they seperate?

thank you i like experiments .

wow crazy man awesome

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".

interesting,,,,,,i will try this,,,,,,,,,thank you for the 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?

HI. Just one question. The used hydrogen peroxide is it totally finished with. Or is it just saturated. So it cant do anything more. Because it could be a big saving if it could be re used after cleaning. Jon

Good video very helpful

Thank you very informative

Wow I enjoyed it

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?

I knew molten SiO2 absorbs metal ions but did not know iron catalist causes the presious metals to drop out of solution. These videos are great!!! I wonder if it would ever be worth it to grind the sand with a ball mill, after it leaves the hammer mill, and then get the metals out of solution by electroplating. The slurry may need to be boiled with sodium hydroxide to disolve silica into sodium silicate and free up more nano gold. Not really sure if it would be worth it tho..

That is one old pulverizer. Amazing how long they hold up.

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

thank you very much

Out of curiosity, have you ever used potassium permanganate for extracting metals?
