    Processing Smelting And Refining Gold Worldgoldcouncil

    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
