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).
The dark blue colored mineral is azurite, while the orange and gold colored material is limonite. The combination makes for a beautiful specimen. More About Standard Types of Copper Ores: In some deposits the oxidized ores and in some the primary sulfide ores are rich enough to work. Yet in other deposits, only the enriched ores of the secondary sulfide zone are profitable.
