Copper Refining Process Steps

  • Refining Gold | HowStuffWorks

    ­The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals.
