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 ...

Apr 01, 2014  Various properties of gold can be utilized for beneficiation depending on the particle size. At particle sizes below 100 μm, the mass forces utilized in the gravity-hydraulic processes weaken, and surface forces become increasingly important (Allan and Woodcock, 2001).These surface forces cause selective attachment through electrostatic, hydrophobic, or adsorptive effects, which are described ...
