A Review on Novel Techniques for Chalcopyrite Ore Processing

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 a sufficient .

Sphalerite: Mineral information, data and localities.

Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).
