On exposure to air, chalcopyrite oxidises to a variety of oxides,
hydroxides and sulfates. Associated copper minerals include the sulfides
bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), digenite (Cu9S5);
carbonates such as malachite and azurite, and rarely oxides such as
cuprite (Cu2O). Chalcopyrite is rarely found in association with native
copper.
