Gold has a special place among metals. It is the oldest metal exploited by man, it plays an important role in world economics, it is highly prized, it was the ultimate goal of alchemists, and it is stored in the vaults of banks. Gold has been used in gilding, to make funeral masks, and for many other uses. Different processes were used for its recovery: panning, amalgamation, chlorination, and cyanidation
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
