Native Copper was the only source of copper until the turn of the century when extraction methods were improved 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 contentSources 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 carbonat
