Processing, smelting and refining gold World Gold Council
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 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 processGold processing Refining BritannicaGold Refining Process Explains every aspects of the Gold Refining Process with its step by step methods, practices and various techniquesGold Refining Process Mineral Processing MetallurgyWith EB Miller’s process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill’s electrorefining process (introduced in Hamburg, Ger, in 1878), it became possible routinely to achieve higher purities than had been allowed by fire refiningGold processing BritannicaOnce the initial processing is done onsite, the gold is transported to an offsite refinery to undergo further refining The purpose of this refining is to remove any remaining impurities The crude gold is melted and then treated with chlorideHow Gold Is Refined: A StepByStep Guide Pease Curren
