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. Since copper is in majority, it is called "copper ore" from where copper is extracted. The iron portion is converted into iron(II) silicate and removed as slag.
