Refining Gold

The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive dor 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. A sample is then taken to a lab for
