Chalcopyrite ( KAL-kə-PY-ryte, -koh-) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale. Its streak is diagnostic as green-tinged black.

To determine the amount of copper extracted, we need to know the mass of chalcopyrite used and the percentage of copper in the ore. Let's assume we have a 0.862 kg sample of chalcopyrite. To find the mass of copper, we need to multiply the mass of the sample by the percentage of copper in chalcopyrite, which is typically around …

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, …
