A Review on Novel Techniques for Chalcopyrite Ore

2012-1-1  The sulfide ore minerals including chalcopyrite (CuFeS 2), sphalerite (ZnS), galena (PbS) provide the major sources of the world’s base metals (Cu, Zn, Pb, respectively), whereas pyrite is virtually ubiquitous as a metalliferous mineral in sulfide ore deposits (Crang and Vanghan, 1994). The first step in recovering metal from their mineral is that of finding ore-bodies in which metal sulfides are present in
