    • How to Leach Gold Ore With Chlorination Sciencing

      The gold is in liquid form in the HCL. Add sodium metabisulphate to force the gold to become metallic gold again. The sodium metabisulphate lowers the pH of the solution, turning the gold liquid into gold powder. Filter the water again using a fine gold filter and dump the water into another bucket and not onto the ground or down the drain.
