BORNITE (Copper Iron Sulfide)

Bornite is an important copper ore mineral It ranks up there with many of the other copper ores such as chalcocite, chalcopyrite, covellite, digenite, cuprite and tetrahedrite As a mineral specimen, bornite is usually lacking Good crystals are rare and thus bornite is commonly known as simply a massive mineral ore...

Copper 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...

Chalcopyrite

As an ore of copper, the yield of chalcopyrite is rather low in terms of atoms per molecule It is only 25%, compared to other copper minerals such as chalcocite, Cu2S - 67%; cuprite, Cu2O - 67%; covellite, CuS - 50% or bornite Cu5FeS4 - 50% However the large quantities and widespread distribution of chalcopyrite make it the leading source of ....
