JA JA MNR & MEV YOUTUBE????? KLINK SOOS KAK STORIES! MORE more almal in Suid Afrika??? IS HIERDIE ALWEER NOG N FOKEN KLUG??? EK WONDER REGTIG OF DIT OOIT DIE WAARHEID IS??? EK GAAN ONDERSOEK INSTEL EN EER KYK!!!
There is no silver in a CD. The reflective surface is made when the CD is in a vacuum chamber next to a nickle disk that is blasted with argon gas. The molecules released from the nickle target adhere to the poly-carbonate of the disc, so the coating is nickle! Plus, the melted poly fumes will kill you!
Hmm looks interesting but as there is no sound etc i have to read fast or pause video to get info, well, all i know is there is liquid in the pan, dont know what it is 🙁 dont know how much base or other chemical you put into it, not even when to put it in etc. amounts would be a good idea, but you should of put the vital info in with your comments. also you did not show the finished piece of metal or even say if you tested it for silver etc. Still looks a good way to get some metal off the discs, however, which metal i do not know. Thanx
What are the chemicals you are using for this method. I want to do it at home to. Maybe you can send me more detailed instructions, with the all the processes that have chemicals added to or in any solution. I have literally thousands of CD's. thanks. Keep the video's coming. Good work
Really…. this is a joke right? Compact discs are aluminum inside… and everyone who believed this video is a sucker. Even in the end you can tell no hno3 was being used (no NOx fumes or anything which would have been produced when redisolving the nitric) …. just hcl dissolving aluminum. Now don't bother with the "well it was a real weak hno3 solution" argument. Even under normal circumstances silver won't just quickly go into solution without heating it anyways…. unless you're willing to wait a few weeks… and still not see it all go into solution. This video should be taken off youtube….. it is a farce!!!!!
About thirty years ago, I had a small silver recovery business. I bought spent photographic fixer from dentists and chiropractors (avg. close to one troy oz. per gallon, for which I paid about $1, when silver was about $20/oz).
I put the fixer into my Rotex electrolytic recovery machine (spinning stainless steel cathode, four big carbon plate anodes, and beaucoup amps of DC passed through).
I also bought old XRay films and scraps of lithographic film by the box (from newspapers).
I put the film through a bleach (potassium ferricyanide and potassium bromide), the process was silver -> silver ferricyanide -> silver bromide.
I then put the bleached film into the fixer I'd stripped clean of silver, which converted the silver bromide to silver ions, which then went into my Rotex, and resulted in pure silver flake which I scraped off the cathode and sent to the refiner for spot minus 10%
I wonder if these discs could have the lacquer washed off in something like acetone, and then be "washed" in (constantly agitated — washing machine, perhaps?) that bleach solution?
It might be easier and more economical, and if so, ought to be nicely scalable.
More click bait! CDs use aluminum, not silver. I can tell by the reactions that HNO3 wasn't used at all and that HCl dissolved the aluminum in the first place (there was no NOx produced at all during the dissolution process…. which would have occured if silver were being dissolved). If it were silver dissolved in HNO3 then you would add HCl, and you would get a different product than the one shown. There would be smaller (curds?) if it were AgCl and it would sink… not float around. Aluminum dissolved in HCl however would produce AlCl upon the addition of NaCl, and was the product shown in the end of the video. Don't waste your time. There is not even a penny of product this video produced, and simply put, the more CDs you processed then the more $ and time you throw away. And to the OP, most veteran refiners of precious metals know the look of different solutions and chemicals. I would not blame you for repeating bad information you heard somewhere else, but you conscientiously lied to us about everything on the video, which makes you just a trolling attention getter.

So how many compact disc would it take to get a lb of silver? Considering how many people throw them away that 200$ a lb, also if you cut them all up into smaller pieces it would take less solution for more discs, sounds like you could make a handsome bid at an Enterprise for recycling people old CDs, time to go pester the neighbors for their old CDs:-)
