Gold Smelting Refining Process

The Miller chlorination process is well know and has been practised for a long time in the gold refining industry. The process consists of chlorine addition into the molten Dore by using an immersed tubing system. Initially there is a slow reaction of chlorine gas with

How to Refine Gold: 2 Major Techniques of Gold Refining ...

It is an electrochemical process which has been applied in many large-scale gold-refining establishments or industries. The principle of gold electrolysis is very straightforward or simple: Dore bar, which is a cast gold ingot at 95% plus purity is used as the anode. The cathode (s) for this electrochemical procedure are small sheets of 24 Karat (pure) gold

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 layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The ...

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 readily than gold
