    Native or elemental copper can be found in nature, but most copper is mined as oxide or sulfide minerals. Chalcopyrite CuFeS2 is one copper mineral that can be converted to elemental copper in a series of chemical steps. Reacting chalcopyrite with oxygen at high temperature produces a mixture of copper sulfide and iron oxide. The iron oxide is seperated from CuS by reaction with sand SiO2.
