Abstract
Potential processes for the recovery of precious metals and copper from diverse types of complex electronic scrap were investigated. Leaching-type processes were not successful, and attempts to physically separate the various gangue metals and plastics from more valuable components were also unsuccessful. The most promising approach was a smelting process, followed by electrolytic treatment of separate precious metal from copper. Recovery of precious metals from the anode sludge may follow conventional procedures. An alternative to the above process is incorporation of the scrap with the concentrate fed to an industrial copper reverberatory or converter furnace, possibly preceded by direct melting to form an assayable bullion and dross.
