  • The Gold Smelting Process Melting, Smelting

    Gold miners have to smelt their gold in order to remove impurities resulting in pure gold Most large scale gold miners send their ore to smeltersArtisanal and SmallScale Gold Mining Without Mercury In many countries, elemental mercury is used in artisanal and smallscale gold mining Mercury is mixed with goldcontaining materials, forming a mercurygold amalgam which is then heated, vaporizing the mercury to obtain the gold This process can be very dangerous and lead to significantArtisanal and SmallScale Gold Mining Without Mercury |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 itGold Refining | From Gold Ore to Doré | World Gold Council
