How Gold Is Recycled From Computers

damb i didnt know pc's give gold crap i should have cept my broken one

lol i make dental crowns

In the presence of nitrate and chloride ions, it will react. Cynanic acid will also dissolved it. So will hydrofluoric acid.

by any chance do u know how much mixture?
i have the hydro acid jus need the nitric.

It is not Carats that measures the purity of gold but Karats. It makes all the difference. Carats is used for diamonds...

thnx for this im going to go to the dump theres all ways old hard drives there :D

actually the mixture is aqua regia

Does anyone know the bath contents the "mixed metal plates are put into?

gold disolves in a mixture of nitric and hydrochloric acid.

How can you dissolve gold with acid; I believe it is non-reactive. ???
