Reduction leaching of chalcopyrite
1983This 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 ...

Flotation of oxidised chalcopyrite
2010The effect of mineral oxidation on the flotation performance of chalcopyrite was investigated at pH 9.5 as a function of pm1icle size and collector concentration. The contact angle of the chalcopyrite pm1icles was measured to inform about their surface hydrophobicity while X-ray photoelectron spectroscopy (XPS) was used to identify the species present ...
