How copper is made material, used, processing, steps

Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.
