Copper ores - DanafloatCopper ores. 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.chief ores of copper,Copper OresCopper Ores. I won't even pretend to know a thing about copper ore deposits ands the geology that goes with it. All I want to show is that an original upwelling of copper bearing stuff (typically some sulfides) gets changed at the top part by exposure to groundwater and air. This extremely schematic picture gives an idea of.
