Selective Volatilization and Recovery of Valuable Metals by Vacuum Carbothermal Reduction of Copper Anode Slime

Copper anode slime produced by electrorefining copper has a high recovery value due to the valuable metals and platinum group metals present. Neither traditional cupellation processes nor hydrometallurgical leaching processes can solve the problem of arsenic enrichment in the system. According to th...
