What Is Copper Ore

What is copper ore mineral? 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.

Chalcocite. Chalcocite is an important ore of copper and a secondary mineral in or near the oxidized zone of copper sulfide deposits. It has been mined for centuries and is one of the most profitable copper ores because of its high copper content (nearly 80% by weight) and the ease at which copper can be separated from sulfur.
