This method of gold mining is responsible for recovering most of the worlds gold supply. Byproduct mining is related to hard rock mining in that open pit or underground mining tunnels are used. In byproduct mining, gold is a secondary find. The main purpose of the mining operation is the recovery of Copper, sand, gravel or other products but significant quantities of Gold exist to make
Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use

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. The Miller process is rapid and simple, but it
