Pyrite is the dominant sulfide in porphyry copper deposits, though it is chalcopyrite that is the most important ore mineral, along with bornite and various binary copper sulfides. In the related porphyry molybdenum deposits, it is molybdenite that dominates. The sulfides in such deposits occur as veinlets or disseminated grains in host intrusions.

Supergene (geology) - Wikipedia

This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.

Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS 2. It occurs in most sulfide mineral deposits throughout the world and has been the most important ore of copper for thousands of years. The surface of chalcopyrite loses its metallic luster and brass-yellow color upon weathering.

Copper Sulphides: Mineral information, data and localities.

Copper Sulfide. Definition. Copper sulfide is a crystalline solid used as a semiconductor and in photo optic applications. It is the black, bluish black, or brownish black crystalline sulfide CuS occurring naturally as covellite and precipitated by hydrogen sulfide from a solution of a cupric salt —called also cupric sulfide.
