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
Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied Oxide ore deposits are frequently of such low grade (eg, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified In this case they are merely shattered by explosives and then piled into heaps for
Gold processing Gold processing Refining: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron Two methods are commonly employed for purification: the Miller process and the Wohlwill process The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more
