Gold Smelting amp Refining Process

Gold Smelting amp Refining Process

Feb 28, 2016 The Inquartation and Parting Process is based on the solubility between gold, silver and copper. Initially there is an impure product obtained by smelting that must be grained to improve the surface area so that the metallic product can be attacked with nitric acid in order to dissolve copper and silver and the leaching residue is metallic gold.
