The anodic dissolution of chalcopyrite concentrate from anode (a mixture of chalcopyrite concentrate and graphite powder) in sulfuric acidic solution as electrolyte was investigated.
At pH<3, the anodic dissolution recctions occurred well, when the electrolytic condition was 1). apparent anodic current density=0.5-1.0A/dm2, and 2). graphite percentage in mixture of CuFeS2 and graphite≥20%.
Anodic dissolution current efficiency for Cu (II) was 80-90%.
