Chalcopyrite is an important ore of copper found in a wide range of hydrothermal environments. It is often associated with sphalerite and galena. It oxidizes to form copper minerals such as malachite, azurite, cuprite and tenorite. Copper liberated from the breakdown of chalcopyrite may accumulate in secondary supergene enrichment zones, …

Chalcopyrite may also alter to iron-bearing minerals because it contains iron as much as copper. Its chemical formula is simple as is common among the sulfide mineral group: CuFeS 2. Pyrite is paler and greenish yellow on the left. Chalcopyrite next to it has much more intense yellow color. Reddish patch on the left is an igneous rock monzonite.

Abstract. Single-phase chalcopyrite (CuFeS 2) is a key reference material in the development of new metallurgical processes to ensure a reliable copper supply.Here, we report on the successful synthesis of single-phase chalcopyrite and its phase behaviour. We further rationalise different opinions previously expressed in the literature.
