Chalcopyrite is a common mineral and is found in almost all sulfide deposits. Fine crystals of chalcopyrite have a unique character and can add to anyone's collection. 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 copper.
