    A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1xS) Often gold and silver are present which may either be associated with the sulphides or are free The gangue particles can consist of a range of silicate minerals from quartz to talc and clays Carbonate mineral gangue can also be present WhenCopper ore usually contains about 05 to 2% copper that occurs in the form of disseminated and stringers The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers The crushed ore is grinded in ball mills to −74 μm size The ore is processed by froth flotation comprising rougher and scavenger cellsCopper Ore an overview | ScienceDirect Topics
