Sources: Sometimes copper appears in its native state. It is found in many minerals, including malachite, cuprite, bornite, azurite, and chalcopyrite. Copper ore deposits are known in North America, South America, and Africa. Copper is obtained by smelting, leaching, and electrolysis of the copper sulfides, oxides, and carbonates.

Of the 170 known copper bearing minerals, 17 are currently used on an industrial scale native copper, Cubornite (peacock ore), Cu 5 FeS 4 chalcopyrite (copper pyrite . Get Price Copper Mineral Uses and Properties. Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity mostly as wiring.
Native metals. Only two metals, gold and platinum, are found principally in their native state, and in both cases the native metals are the primary ore minerals. Silver, copper, iron, osmium, and several other metals also occur in the native state, and a few occurrences are large enoughand sufficiently richto be ore deposits.
The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the mostused metal in the world. The special properties of conductivity, malleability, resistance, and beauty make it so popular. The main
Copper Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite. Minerals in the oxidized zones include malachite, azurite, chyrsocolla, cuprite, tenorite, native copper and brochantite.
Copper is a mineral by definition because it is a native element on Earth. Its applications range from practical/utilitarian to decorative/ornamental. It efficiently conducts electricity, so it is frequently used in wiring. Copper is also made into alloys with other metals. Combined with zinc, it makes brass. Mixed with tin and zinc, it creates
