I like the hcl peroxide process, I had some copper with gold in it and welded to steel by accident. I used the AP process to dissolve the iron and copper, leaving me with some gold in solution and some as solids. The AP drop with smb works great. Thanks for another trick for recovering gold
The tital of you video is what drew me to your sot. I myself do gold recovery (from electronics) also from jewelry. After listening to you and hearing your take on the economy I subscribed. Nice to see there are others smart and not afraid to speak about the fact they are killing our economy with all the free money printing crap they are pulling. Thank you for the vision about gold refining as well .
H2O2 is hydrogen peroxide, Muriatic acid is HCl in acid solution. H2O2 released O2 (oxygen bubbles) and metallic gold dissolves as HAuCl4 yellow solution. It crystallizes as a yellow solid, HAuCl4.3H2O, gold(III) is not metallic now, but a salt complex. There after he will reduce Au(III) to metallic gold with sulfur(IV) dioxide. SO2 )gas) gives 2 electrons to gold(III) and ends up as sulfate, thus been reduced to Au(0). Impurities will remain in solution. He just have to rinse Au(0) with H2O to separate impurities from metallic gold.
@@vperez4796 Yes, but tetrachloroaurate(III) is yellow, and metallic gold is a dark precipitate. Therefore, the gold has to be present as a colorless species at the point that the solution turns clear but before metallic gold precipitates. The question is what that species is. I was speculating that contains gold(I), which is plausible as an intermediate oxidation state if it's gradually being reduced by the SO2.
wow - super cool video showing how this is done , thanks to people like you who openly share and contribute positive and informative content like this - awesome work :) thank you!
Awesome reaction Sreetips!!! Yes very impressive and spectacular!!! Thank you for always providing great content, information and education over the years!!
Absolutely spectacular! Very well presented, thank you Sir. It has been returned to its state at conception…well, pretty close to it anyway. It’d be neat to see a sample under high magnification.
This was really cool. I knew this was a way to purify gold, but this is the first video I’ve seen doing it. You’ve inspired me to give this method a try on my next batch of gold.
the pink / red colour of the gold is from the light reflecting off the gold particles, way back when they used gold on stained glass to make shades of red coloured glass. a bit of gold history for everyone :)
Surface plasmons; light activates a metal surface, creating waves in the shared valence electrons. The waves act much like a diffraction grating, reflecting light of specific colors. For many years, Ruby glass was though to be gold dissolved into glass, but it turns out the gold exists as nano-scale spheres suspended in a clear glass matrix. This gives us the pinkish solution.
Pink/purple are the colors of gold. I accidentally added too much silver one time and the Inquarted gold fell apart into a powder. It had the most fantastic looking color layers in the liquid after settling completely. From blue to purple to red to pink. It was awesome and I’ve never been able to reproduce it. Long ago when I first started refining.
Yup, this is how it works in the modern monetary system. I don't like the term "printing money" because it was historically used to mean something different: it used to mean *government* literally printing banknotes and keeping them. The result was akin to taxation, just done differently. Today, money is created by taking loans. As long as interest rates are low (and they are stupidly low), lots of loans are made, and this increases money supply. But no evil "them" is actively doing it (or keeping it), the new money goes to whoever is willing to borrow.
Nixon should have never taken us off the Gold standard! This fiat “currency” (created by the PRIVATE Federal Reserve) will be the death of the Republic! END THE FED!

He had no choice. If he didn’t do it then all of our gold (currently 8000 tons) would have left the country. After WWII we made everything and the world paid us for it. But they paid in gold. Our reserves soared to 22,000 tons. If they tried to buy our goods with their currency they would be left empty handed. But as we began to spend more than we took in back in the 50s and 60s our gold reserves tumbled. Foreigners noticed this and wanted gold instead of dollars. They showed up with billions in paper dollars and demanded gold. We had a place open that allowed that. But they closed that window in 1971 when the president, who realized that all of America’s gold would be gone in very short order, so that the currency could no longer be exchanged for gold. No one batted an eye. And that is when it all started. Printing money without restriction. Our fiat system will fail with 100% certainty. Not what I want to see happen. It’s bad for everyone. And the public don’t realize this nor do they care. Try explaining it and you’ll lose their attention very quickly.
Hydrogen peroxide 3% in Denmark costs around 3,5 dollar per 250 ml And yeah.. nitric acid and all kinds of nitric salts are banned for private use by our terror law. And yeah.. sulfuric can’t be bought over 30%. I’m just ranting 😎 nice video sreetips 👍
It really gives me hope to be able to replicate a similar process by watching this. DG hydrogen peroxide 3% is in great abundance to me. I like your style of cutting costs using consumer grade chemicals. Also, no wedding rings were harmed in the filming of this process!
@@bormisha this isn't the type of chemistry to be bothered with high purity expensive reagent. You gotta know when it's important to spend money on the good stuff
@@jacobkudrowich This statement is applicable to all areas of life as well! I struggle with this. I keep buying the nicest or top 10 percent of whatever i am interested in ... When the reality is that i could be just as satisfied and save much more money by buying a much cheaper product.... It is a hard lesson to learn.
Love it. The commentary on inflation. Still and so much more relevant today. We’re near a banking collapse across the country, a liquidity shortage and a global reset.
That's pretty cool. I assume this wouldn't work well if the gold wasn't pretty pure already with no silver mixed in but seems like a good method for secondary refining, especially since hydrogen peroxide is cheap and has no special hazmat requirements to ship up to 12%. One thing is it starts to break down much past the boiling point of water so you may have lost some that way.
@@sreetips Maybe inquart with copper instead of your usual silver. Or don't inquart at all and just dissolve the carat gold directly. I'm thinking you'll get Silver Chloride precipitate, and you know how fun that is to filter. :-)
This is a bit troubling. Because I don't have access to nitric, I have used hot HCl + H2O2 to take non-precious metals into solution, with the filtered solids assumed to contain the gold. I was not aware gold was soluble this way. Obviously I have been losing gold into the waste stream. I learned something.
You may have dumped a colorless AuCl dispersion. I suggest you keep all metallic waste solutions. Let the it evaporate into a vented hood. Check if the acidity has decreased (use pH paper) you can use active metal filings, like metallic Zn. Metallic Zn limings shall oxidize to ZnCl2 and the Au(I) shall be reduced to metallic Au. Careful where you dump metallic waste, some organizations can get very nervous about that. I can safely argue that Zn(II) is part of our enzymes and also comes in vitamins supplements. Most living beings (vegetables and animals) use Zn(II) for their metabolism. IF YOU MUST DISPOSE of ZnCl2, I suggest you use sodium bicarbonate to precipitate Zn(HCO3)2, a white insoluble solid, Dry it out, keep it dry in a plastic container. Large amounts of metallic salts in the ground or rivers are not acceptable to most legislations, check out in your local library about state regulations. AuCl3 salts are reduced to Au nuggets by bacteria in the rivers and down the bottom of the seas.
HCl with H2O2 method is an environmentally friendly way to reduce Au(III) (aka AuCl3) to metallic gold. H2O2 is oxidized to O2 +H2O, the safest possible byproducts. In an alternative method where they use HClO, aka bleach, you precipitate copper (CuCl2) from electronic fingers as Cu(OH)2 , a greenish solid left in the filters. CAUTION; The moment you mix HCl with bleach, chlorine gas evolves (used in WWI as poison gas). You better stick to muriatic acid with hydrogen peroxide method. WARNING; Using H2S gas produce SO2 and H2SO4 in acidic conditions.
@@joestreet7036 Better don't store HNO3 at home. Some safety issues and also legal issues may apply depending on the State you live in. Be sure you read the legal regulations about HNO3 in your local library. Besides the regulations, I must warn you that concentrated HNO3 damage the human skin and possibly provoque burns and wounds. In addition hot HNO3 is a strong OXIDIZER, that is why you use it to dissolve metals. You MUST be a qualified technician to store and/or handle this acid. In addition any HOT strong acid like muriatic, is equally dangerous in to your health. Besides HCl is an oxidizer in the presence of Hydrogen Peroxide. Did any YoUTuve channel warned you about the above the precautions stated above?
Brilliant Mr Sreetips......A little tip for you, when working in labs with reagents always hold the bottle with the label in the palm of your hand, then if someone forgets to rinse it none of use get contaminated....all the best mate and thanks.
If you're looking for interesting new gold precipitants a try, try using sodium nitrite (recommended in Hoke's book for separating gold from PGMs).After filtering, remove as much HCl as you can from your solution and then add NaNO2 powder bit by bit until the solution decolorizes. It drops gold from solution but leaves all of the platinum group metals in solution-- worked a treat on some crude gold powder I had!
Wait a minute…I’ve always been told to remove any potassium nitrate, completely, or NO GOLD DROP will occur. Is sodium nitrate a replacement for nitric acid, too? I know that a two year old video with comments will probably go unanswered, but I thought I’d give it whirl. 😊
Hey sreetips, thanks for another great video! I've got a question for ya. Could there be any adverse byproducts of applying this method to black sand containing very fine placer gold? As far as I know, black sand is mostly iron bearing rock (hematite and magntite mostly). Love your stuff, bud, keep up the great work.
wow this is along the lines of my question above. I see videos of alot of panners who discard so much "flour" gold just because it's time consuming to clean up.Hematite being magnetic would be easy enough and since sand is basically glass, chemical extraction should be doable. My thought with clay sediment is to dissolve/ suspend the gold, let the dust settle and pour the gold off the top.
@@MH-ql8ue around here both magnetite and hematite carry a bit of gold. I need a reagent to precipitate the gold out after I used the same process as the video.
Every time I see your gold in solution I think back to what the lube oil samples from the main reduction gears looked like. Always called it clear and bright.
Clear and bright with zero BS&W! One destroyer that I was on, a messenger opened the wrong valve and allowed one of the settling tanks to gravity flow into the main sump on the reduction gears. It ruined the journals on the turbines. Had a civilian tech come to the ship in Naples. I remember that the LP turbine rotor journals looked like rusty pipes! He rigged an air motor to the turbine rotor and a dummy bearing and actually cut the journals and fitted new bearings. That was aft engine room. It got us home from across the pond.
@@sreetips We wiped out the aft bearing on our low pressure turbine in #2 engine room (DDG 12). They stopped and locked that shaft and reworked the bearing with a razor blade until clearances were in spec. That bearing was still running cool after a trip from American Samoa to Pearl Harbor and back to San Diego. I really miss the steam plants. MM3, USS Robison, DDG-12.
It would be interesting to see an assay of the material going into the process, and then again at the end of the process to see the degree of refining taking place.
Wow thank you so much for that. Fascinating to see the oxidation power of hydrogen peroxide taking over from nitric acid. Any idea of why not all of the gold powder dissolved? Maybe that portion was lower purity or contained a trace impurity level that prevented dissolution? Maybe it was coarser or microscopically had a low surface area form that prevented efficient dissolution? Peroxide can be tricky as it is so ready to react with anything, any impurities in the water or solids can result in a poor efficiency. Amazing watching the sulphur dioxide slowly taking effect and finally precipitating the gold. I would think we were seeing the SO2 react with residual peroxide in solution as SO2 is reducing/peroxide is oxidising. The inflection point was beautiful.
@@sreetips No worries - thanks as always for the reply. Thank you again for this demonstration of this reaction. Really enjoyed the precipitation of gold with the sulphur dioxide.
Really great video, love watching your refines. Could this have been dropped with just standard SMB ? i know you mentioned it is a cleaner drop with the gas so just wondering. sorry for the newbie question, still learning the trade. many thanks Weremouse workshop
You do this so easily. I just tried to drop my gold out of AR and when I added SMD to my solution it turned dark black and then it turned right back to yellow color it was prior to SMD. Not sure what happened so any opinion would be well received. Thanks for everything you do.
You had excess nitric acid in your solution. The SMB dropped the gold, and the AR re-dissolved it. Use urea to denox the solution. Best if you do what Streetips always does: Start with the HCL and only add as much nitric as needed to dissolve the gold -- no more. That's why he doesn't need to add urea. Any tiny amount of excess nitric he added will be used up by the SMB. I guess as a alternative you could keep adding SMB to your solution until the nitric was used up re-dissolving your gold. It's just wasteful, but eventually the gold will drop out and stay.
@@guygordon2780 thank you sir for the great explanation and this makes sense to me. It looked so awesome when it turned that dark color then the wa wa wa moment. This will help me as I left it alone so now I can go back to it hopefully I can bring it back out of solution. Thank you again I really appreciate the help.
@@sharkozym Any time you get a black powder there's a good chance it contains precious metals. So don't dispose of it. Add it to your stock pot or dissolve it with AR. You absolutely need to use a drop of stannous chloride solution to test your solutions for precious metals before you add them to your waste bucket.
Wow, that was very interesting and some work doing all that. Thank You. I will leave the Science to you. Nice Instructional video. I like to learn new things no matter how old i get. Be careful with all those Chemicals. Take Care.
Wow amazing reaction. Ive collected a good amount of gold flakes from electronic scrap and went ss far as buying the Nitric Acid = 66 % but chickened out on carrying through with the recovery
Witchcraft!! You're an Alchemist! LOL, precipitation always fascinates me, thank you really enjoyed this and your excellent narration that goes with it. Having had to wear gloves in my work what I use to do to help with the sweating is cut small holes in the backs of the gloves. Of course I didn't work with the acids that you do too. Thought I would mention it. Thanks again, very fascinating.
I just want to thank you for this video, I live in a country where acids are not easy to come by, in particular nitric acid, even nitric salts are not easily available for the public to buy to make poor man's aqua regia. So I used this method to dissolve gold foils from pins after I had dissolved base metals. It was my first e waste refining attempt. I am just waiting for the shops to reopen so I can go get some smb to drop the gold from solution.
Would you be willing to tell the ingredients? And I use electrolysis with non magnetic stainless steel as the sacrifice anode. Works good but you have to geek your eye it very closely, because otherwise other metals will get in the mix, in this case its copper, nickle, aluminum platted with gold and silver. You just need a 12 volt power supply with the built in serge protector I started using salt and house hold distilled vingar but my mixture tended to turn brown, then I used baking soda and vinegar, I have not refined one bit of it yet because the acid is expensive and we only shop Amazon.
Sweet! I've never tried hydrogen peroxide and muriatic. I made SO2 gas by adding an excess of powdered sulfur to sulfuric acid and bringing it to a boil.
It is possible to find SO2 gas in cylinders. I think it is used in the food packaging industry to sterilize. It may be prohibitively expensive, but the technique of bubbling the gas into the solution to precipitate Gold is a pretty good one.
@@sreetips I see... Did not know about the rental. I thought it would be purchased. It is toxic, though, and could be used to harm others, or could do so unintentionally as well. Not surprised that the sale is restricted.
Same. It was devastating. It was hard to view the suffering that the quake caused. Prayers for relief for the people. The earth is a dangerous place to live.
When you hit 100k subs I predicted that you would hit 250k in 2022 (about a year). I think that's a way low number, I think you will 400k to even 500k subs next year or 2022!! If that happens then in less than a year from that you will hit the BIG ONE MILLION SUBS, in 2023!!! You Rock Sreetips! I Hope You Do It! Have a Great Day My Friend!!
That would be something Shane. I’m swinging the axe, but no chips are flying. These videos are hard work. I’m wiped out for a day or so after cranking one out. The problem: refining precious metals appeals to a narrow audience. But I like your enthusiasm!
@@sreetips Pace yourself so you don't burn out! Thanks to you and your professional videos, the audience is growing and growing quick!! I know you don't talk about it, but can you imagine the financial increase from RU-vid when you have a million subs. I know your not doing it for that... well not totally! Lol 😆 It'll help keep your workspace nice and clean and with the updated tools you'll need.
My advice, try direct pouring thionyl chloride into solution. It instantly hydrolizes in water with sulfur dioxide formation in situ, hence no need of any additional equipment and processes.
Hydrogen peroxide! Nice. I have rocks with super fine platinum group metals. I will not use/make more than a tiny amounts of AR (just enough to dissolve samples for testing). This could be a good alternative.
It's not just the US dollar , the whole planet has inflated. There saying a 5-6% increase just since Xmas & it's going up again! I'm in Ontario 🇨🇦 and especially food has jumped, it makes me sick man!
Just remember that the increase in prices you are seeing is the result of inflating the money supply (printing money out of thin air that is backed by nothing). And think about this: if you need money to buy something then you must either go to work and earn it, or sell something. But our friends in high places, if they need money, they can just print it. And this never gets talked about. Most common folks think inflation is caused by greedy merchants raising prices to gain more profit. Our “friends” in high places create the inflation that causes prices to rise, and the public ends up blaming the merchant. It’s insanity!
you know for once i like to see one of you guys that are doing videos on gold recovery to show what you do on handling all the waste step by step.would be a better way showing for gold recovery
There is an episode of Monk, where someone dissolves gold and then makes ink with it, which is used to write a bunch of journals and hide the gold. I watched the episode like 20 years ago, and it still sticks in my mind.
One thing I noticed that is missing from the discussion though is the fact that people think since the end of Bretton Woods (the day the French gunboat sent here to demand their gold left New York Harbor empty-handed) people think that the dollar was backed by nothing when in fact Kissinger secured a deal with the Saudis where all oil was purchased with US Dollars called petro-dollars which effectively backed US dollars with oil because the world runs on oil and it's been that way ever since until just recently (like a week or two ago) and now it truly is untethered from anyting and I suspect not long for this world
All is not well. But all is as it should be. Forget about the narrative and start putting metals away. You’ll be glad that you did, and sorry, wishing that you had, if you don’t. Don’t take an economics degree to see what’s coming.
your comment about H2O2 costing more for two containers - it is because the manufacturer need to pay more for two containers, takes more time to fill and bottle two bottles, and it costs more to transport as well.
The unmitigated printing of currency is one of the most despicable acts. This practice serves to show you exactly what they think of your time and effort. They are effectively telling you that you are worthless by doing so. Preserve your wealth outside the system and educate people to do the same!
Don’t hold your wealth in paper dollars that are melting value away faster than a snowball in July. But rather store your wealth in metals that will rise as the paper declines. If you need some paper to buy food or pay rent, then sell a little of your metal. Soon people will be falling over themselves to buy it from you. But only if you had the insight to buy it now, while it’s on sale.
I am strictly limited on general information exchange on eBay. They watch it like a hawk to see if users are trying to deal with each other off their site. Big Brother
is any one method better than an other? I watched one the other day where you made an acid, had to bring up the ph, ran out, had to make more... ive seen lots of SMB granule videos, personally, I like watching the SO2 gas precip myself.. is anyone better than the other? is one just cheaper therefore preferred?
Adding powdered SMB straight in is the easiest and most convenient. Ferrous sulfate is good if other metals such as platinum are in with the gold because ferrous sulfate will precipitate the gold, all the gold and nothing but the gold. But it bulky and cumbersome to set up. SO2 gas is supposed to be superior to all other methods but it’s a huge pain to set up the gas generator. Oxalic acid is a “polishing step” and the gold must be high purity to begin with. And it’s a pain because the of the pH adjustment and having both solution boiling for a successful precipitation. I like SMB because it’s simple and easy.
