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 ...

A rock breaker has been installed to ensure that all +800mm feed ore is broken to -800mm size, in line with process specifications. From the tipping bin, the ore is fed onto a 150mm vibrating grizzly using an apron feeder from which the -800+150mm material is deposited into a jaw crusher, which reduces the -800+150mm material to a topsize of 210mm.
