Yes, adding H2O2 to the mix very much accelerates the reaction. Back in the 70s, when I was working a precious metals recovery lab, I was in charge of the first stage of recovery, which included crushing the incoming material, stripping the gold and whatever else was going to get dissolved with the cyanide and preparing the solvate for the chemist to purify. We typically performed batches of 30-50 pounds of scrap. The solution was started with about 10 gallons of 130F DI water, 2-3 pounds of cyanide (sodium) and then to start the reaction, 100ml of 30% hydrogen peroxide. It was important to have a ventilation system for this and for extra protection we covered the bath because of the violent reaction of the H2O2 and the dissolved NaCN. We would have totally stripped parts in under 1 hour. As for the cyanide, we used a type that was briquetted. There was almost no dust when dispensing the cyanide for the job as a powdered cyanide would generate. I practiced *extreme* safety then and probably by 2019 standards it would be considered not good practice. Everyday one of my duties was to wash down the entire lab area I worked in. Wash all benches, glassware, fume hood and mop the entire floor. The entire laboratory was under negative air pressure (below atmospheric). The doors were difficult to open from the outside! I appreciate the small scale demonstration here. It brings back memories of one of the best jobs I had. We were capable of handling 500+ pounds/day of scrap (not gold!) for whatever recovery the chemists had predicted. I'm not a chemist but I learned a lot of gold/silver/platinum chemistry from that job.
+NurdRage hey, I had a quick question. I was wondering, how do you predict the product of reactions? It would be cool if you could at least point me in the right direction because im having trouble going about it.
Off Topic: Some years back I worked in a factory & our building had a designated cleaner responsible for everything, including making sure there was boiling water & milk available for us to drink - with our tea/coffee. At that stage in my life I drank neither tea, nor coffee. However, one day people in our building were complaining that their tea/coffee seemed very "gritty"... Questioning the cleaner, he said that the urn had calcified somewhat with the build up of tap water over the years, so they took it upon themselves to take the urn to the heat treatment shop & use the Sand Blaster to get rid of the calcium build up... Fortunately for everyone in the shop, they were ALL very lucky that no-one got sick (or worse), as the heat treatment shop used ALL types of Salt Baths, including Sodium Cyanide salts, for a controlled heat treatment process... That day could have ended very badly... :/
FYI Gold is complexed with Sulfite in soft gold plating solutions for jewelry. Thiosulfate and thiourea also complex with Gold, and like cyanide, lower its EMF so Oxygen can oxidize Gold metal into solution. DMSO also complexes but not sure if it dissolves Gold metal.
This is used in industrial gold processing? Fuck, I'd hate to work there! In poor countries though, they just flat our pour mercury all over the place to bond with the gold. It pollutes the shit out of the land. Can you do a video on that?
Flexicone new leaching technology. For the processing of refractory gold-bearing refractory and sulfide ores, Flexicone has developed a unique enrichment technology. The technology includes the processes of ultrafine grinding and oxidation of sulphides, extraction of released gold and platinum group metals by centrifugal concentrators and leaching of gold, silver and palladium.
Wow...dissolve gold into an aqueous cyanide solution, and it looks clear. It'd be an interesting way of smuggling gold out of an area, if you could get the solution to hold enough gold! (Crime caper: crook steals the gold, dissolves it, flushes it down the toilet, where a plumber co-conspirator has already re-routed the sewer line! Bet nobody would see that coming!)
Hey NurdRage, from what I understand you needed oxygen to promote the reaction but didn't want to use hydrogen peroxide? If this is true, you might have thought about getting one of those fish aquarium "bubblers" (the kind with a stone at the end to make it fizzy) and drop it into the solution while it was mixing.
+stonent Thumbs down stopped working since google took over. I'll like my own comment and you can try to give it a thumbs down back to zero. It won't work. The button is useless.
Why? You have no reason to believe the high pH is going to interfere with the metal chelation process, it may actually do better under those conditions than neutral or acidic conditions.
Two questions: (1) Why does the beaker slowly turn and move during the timelapse? Just vibration from the stir bar? (2) Where do you get such fine gold powder, or did you make it? And if you make it, how?
Stop comparing nurdrage to cody's lab! It's like comparing the brilliant blazing sun to a wet squishy paper towel wrapped around something gross that you don't want to open.

That’s a very slow reaction. I used to work in electroplating and when we chemically removed gold layers they dissolved much faster. The stripping solution contained mostly sodium cyanide. I’ve always wanted to know what exactly the other ingredient was but that is kept secretly by the manufacturer.
+fpm1979 From what he said it was more than likely H2O2, or Hydrogen peroxide as that degenerates into water and oxygen gas, which'll act as a catalyst.
could you do a video on the smash glow properties of wint o green life savers. I'm pretty sure it's the winter green crystal that do this. I have seen a few chem videos wintergreen but none that show this property
That's superbly interesting! What sort of scale (volume & time) are we talking about for industrial mining with a weaker solution? It sounds like a really long process (though it probably is easy to automate)! Learnt something new today, thanks!
Hey NurdRage i have a question for you: in the video you used 2 grams of cyanide but when ive calculated this ive found that you only need 0.288 gram www.siz.co.il/my.php?i=nudi2oynayxg.png so my question is why did you use way more cyanide then you need?
could you make an video about gold plating without cyanide starting from chloroauric acid? i read about using sodium sulfite to form a complex but i dont know how its done...
Your video about making sodium cyanide is deleted, is there’s a way to get a copy. I watch that video a couple times just to see your warning at the introduction. It was hilarious. Please let me know.
I started watching your (edit: excellent) videos to refine and extract gold but I am terrified of what I think I know about sodium cyanide! I'm not sure how dangerous this really is.. handling, neutralization etc.. tips welcome!
I would be very interested to see a video on recovery of gold from activated carbon after cyanidation. I am having allot of difficulty finding that information and even more understanding it.
Or perhaps if you could steer me towards the most cost effective recovery method from complex sulfide ores. :) (Gold,platinum,silver,copper,lead,nickle.....sulfides, lol)
I guess you can retrieve the gold anytime by reacting it with Zinc dust. Zinc can replace the Gold atoms in the co-ordinate complex. I wonder how we can retrieve Silver from silver nitrate without the Tollen's test method.
As long as all I do is filter off the cyanide solution from cons. Can I put same cyanide solution on next batch of cons? I just started using cyanide. 5-6 grams per liter of water, Ph 11, temp 60-70 F, mix and air 4 days. Does warm or hot work better and shorter time? Zinc powder, then filter, rinse good with hot water, then into hot HCl, filter rine hot water, then nitric/water hot, filter rinse then into AR.

Thanks for all what you share with us.i want to ask you about how to precipitate all the gold from cyanide sodium solution . With smb or zink or electrolisis
Nurd rage I was inspired by your video to take apart Li-ion batteries. Also on a related topic o have a problem, I put the material I thought was lithium from a dead Li ion battery in hydrochloric acid, before this I heated it in a steel container (previously containing zinc from melting) to see if it would melt but it just crumbled a bit but had the destinct red flame I wanted to make a flame colorant for pyrotechnics i.e zinc chloride but when added to the HCl it make a noctious gas and a dark green liquid and I can't find any info on it PLEASE HELP
Could this process work with potassium cyanide? Can you speed up the process by bubbling oxygen through the solution? Say for instance with an oxygen concentrator.
Hey can someone explain me a thing a did:so i held a can o Deodorant against a piece of cotton and filled the cotton with the Deodorantafter that i put warm water on it and it looked like it boiled,any help is appreciated
Here at my high schools lab I am a lab tech and in the mornings I mess around with stuff a few months ago I tried to make Brass but we had nothing to heat the metals hot enough then I thought wait make the brass chemically. I have the brass in solution now but I do not know how to bring metallic brass out of solution, what would your opinion be?
You're not going to be able to do this nicely but if I may make a suggestion, I would try to iobtain the oxides of the copper and zinc (you should be able to find a method for this somewhere) and then mix them together with aluminium powder to make a thermite. I'd try igniting such a mixture on a very small scale whatever you do because ordinary copper thermite is mildly explosive at larger scales.
Dear Nurdrage, I was doing your penny to 'gold' experiment and I made my own ZnCl. In I put the penny in the ZnCl and heated it up. I heard hissing and was wondering is that Cl gas and am I going to die? If not what was it? I commented here because that was a rather old video. -Sam Fultz (Fake name for those weirdos out there wondering) ;)
+Adam Lang this is his own amateur lab. presumably, he works in a professional lab. or he's a chemistry undergraduate who bartends, but likes chemistry so he makes videos in his spare time.
***** If you are joking, that was funny(no sarcasm). If not, gold is pretty unwilling to take electrons so if you put in a more reactive metal, ie aluminium, the aluminium will gladly kick the gold out of solution(reduce it) and form an aluminium salt.
But you ain't workin with gold! Your workin with gold cyanate or whatever it was, from the seems of it the gold atoms are held in a molecule with the cyanide. CBA to look it up and tell u proper right now. Go on that link to the wikipedia you'll find right out about thast shit
Pseudobean Machine Basicly the other metal atoms want to bond to cyanide more so they kick the gold out and go in themselves. Basicly the other metals steal the girl from gold.
