摘要：

Mechanical activation by autogenous milling has previously been shown to improve leaching kinetics. In this study autogenous milling was conducted simultaneously with ferric chloride leaching. A sequence of products was observed, with chalcopyrite beings replaced by synthetic nantokite (CuCl) and the nantokite being more gradually replaced by synthetic eriochalcite (CuCl2 . 2H(2)O).
