desulphurization flotation kinetics pyrite modeling acid generating potential 1. Introduction Throughout the world, many mining operations deal with sulphide ores to extract various valuable minerals such as chalcopyrite (CuFeS2) for copper, sphalerite (ZnS) for zinc and galena (PbS) for lead. Some gold and silver ores are also sulphide rich.
