      The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting By 2000 bc the process of purifying goldsilver alloys with salt to remove

  • Processing, smelting and refining gold World Gold

      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
