copper metal is usually produced from minerals by hydrometallurgical methods. another source of copper is recycled copper and copper alloys that accounts for 4050 of premanufacture copper production. this copper is recovered by simple melting of high purity scrap and smelting or refining of impure scrap.
the copper in these products is mostly tough pitch copper cathode copper into which 100500 ppm oxygen has been dissolved during melting/casting. the remainder of unalloyed copper production is in the form of oxygenfree high conductivity copper with 510 ppm dissolved oxygen. these pure copper products account for about 70 of copper use.
