Hi everyone!
I'd like to discuss how to recover gold from a cyanide solution.
We polish the jewels using Sodium Cyanide and Hydrogen Peroxide and after mixing them happen a ''bombing effect'' that makes the jewels cleaner!
I store the solution and till now I've treat it with sodium hydroxide and some aluminium.
The result is that I have accumulated a quantity of sludge and I'm not sure how to get the gold from it.
I don't think aqua regia process would be a good idea... because of the cyanide...
Does anyone has any idea how to treat this kind of gold waste?
Thank you
