***copper remains in gold The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
Copper in the USA: Bright Future Glorious Past Copper Producers. At the beginning of copper''s flow through the economy are the mining companies, which process vast quantities of lowgrade ore, mostly from openpit mines in order to produce copper. Approximately two tons of overburden must be removed along with each ton of copper ore.
