Copper is found in natural ore deposits around the world. The most abundant ore are chalcopyrite and bornite, which contain both copper and iron sulphides. These account for about 80% of the worlds known ores. We supply ores with copper content within fairly narrow ranges of specifications to satisfy our customer needs
The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of the minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS). 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.
