­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 A sample is then taken to a lab for tests or assays that measure

The crude gold is melted and then treated with chloride This converts any foreign elements or minerals still in the gold into chloride which will then naturally drift off the gold The result of this process is 995 percent pure gold The final step is to cast the gold into electrodes or anodes and place them in

Dr F B Miller of the Sidney Mint created a process to purify gold using chlorine which forms chlorides with silver and other ore impurities but leaves gold unaffected The refiner places the ore in clay pots heats the vessels in a furnace and pumps chlorine gas into each pot After cooking for a few hours the refiner retrieves the pots

Gold bulls were disappointed that the price did not break through the 2000oz ceiling nevertheless the current stable price run has helped to maintain a strong interest in gold projects Gold processing has a couple of unique features
