2020-7-24In the UK, copper is mainly used to make semi-finished products called semis which are made from the refined metal, either as pure copper or as copper alloys. They can be in the form of wire, rod, bar, plate, sheet, strip, foil or tube. Over half the copper is sold in the form of cables, wire and tubes. Much of the rest is made into alloys.

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
