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 ...

How The Gold Refining Process Works Global Bullion

The Refining Process. Refiners start with one of two types of gold a dor bar or scrap. Dor bars are produced by miners and are about 80 percent pure. Refiners increase the purity by separating the other precious metals and less precious metals that are mined with it. Using induction heating, dor bars and scrap are turned into molten metal.

Process Of Refining Gold My Gold Guide

May 15, 2018 In the Miller process, unrefined gold is first melted. Then, chlorine gas is passed through it. The gas turns other metals and impurities into a solid form, making it easy to separate them from gold. Even after this process, the gold that is obtained is 98 pure. This gold is then further purified electrolytically, thus removing platinum and palladium. Cupellation
