WebCopper is present in the Earth's crust mainly in the form of sulphide minerals such as chalcopyrite (CuFeSz), bornite (Cu^FeS,) and chalcocite (Cu2S). The concentration of these minerals in an orebody is low, and typical copper ores contain from 1/2 % copper (open pit mines) to 1 or 2% copper (underground mines). The naturally occurring mineral binary compounds of copper and sulfur are listed below. Investigations of covellite (CuS) indicate that there are other metastable Cu-S phases still to be fully characterised. • CuS2, villamaninite or (Cu,Ni,Co,Fe)S 2 • CuS, covellite, copper monosulfide
