The slurry that remains after this process has a very fine particle size Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand) Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching process...
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...

How Is Gold Purified? Gold can be purified to its most highly-refined state through the Wohlwill process, which was invented in 1874 by Emil Wohlwill In this electrochemical process, impurities are removed from the ore by first melting it with chloroauric acid, which serves as an electrolyte, and then passing an electric current through it...
