Processing smelting and refining gold World Gold Council 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 produces gold of only about 995 percent purity The Wohlwill process increases purity to about 9999 percent by electrolysis.Gold is smelted in a crucible furnace to produce unrefined bullion In smelting base metal impurities are oxidised and absorbed leaving the precious metals to be poured into ingot moulds Smelted gold is then refined Several refining processes are used in Australia chlorination electrolytic and aqua regia.
