Production Found in ore deposits around the world, copper is extracted using two basic mining methods: open pit and underground mining. Openpit mining is the most widely used technique.

About 80% of the world's primary copper comes from ores in which copper is present as a sulfide mineral, for example, chalcopyrite (CuFeS 2) (the most abundant copper ore), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S). These ores contain typically only about % copper.
