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 aforementioned minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS).
There are two main copper ore types of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined. However, the most common source of copper ore is chalcopyrite, the sulfide ore mineral â it accounts for about 50 percent of copper production.Copper sulfide ores are the most profitable types of ores.oth ore types can be economically mined.
