mineral processing of sphalerite

Sphalerite - Wikipedia

21 rows  Sphalerite ((Zn, Fe)S) is a mineral and ore of zinc. It consists largely of zinc sulfide in crystalline form but contains variable iron; when iron content is high, sphalerite is an opaque black variety called marmatite. Sphalerite is found in association with the minerals galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite and fluorite.

mineral: Sulfides In another sulfide structure, sphalerite (ZnS), each zinc atom is surrounded by four sulfur atoms in a tetrahedral coordinating arrangement. In a derivative of this structure type, the chalcopyrite (CuFeS 2) structure, copper and iron ions can be thought of as having been regularly substituted in the zinc positions of
