The principalgoldminerals that affect the processing ofgoldores are nativegold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution)gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractorygoldores are submicroscopicgold, the Au-Ag tellurides, and very fine-grainedgold(<10 µm) locked ...

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.
