Reduction leaching of chalcopyrite

1983
This study has been concerned with developing novel reduction leach methods for chalcopyrite (CuFeS₂) copper concentrates. It has been found that chalcopyrite can be essentially completely converted to chalcocite (Cu₂S) by leaching in strong copper sulphate solutions at elevated temperatures, using either pressurized hydrogen gas or metallic copper ...
