Chalcopyrite is a copper iron sulfide (CuFeS 2) mineral with a brassy to golden yellow color (Fig. 1.36). Chalcopyrite contains 34.5% Cu, 30.5% Fe, and 35.0% S. The mineral is the principal source of copper metal, and one of the major source of sulfur. The mineral also contains traces of elements of gold and nickel and recovered in refinery.
