<h3>Processing, smelting and refining gold World Gold Council</h3><p>From ore to doré.  In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the gold migrates to a negatively charged electrode (cathode), where it is restored to a highly pure metallic state, leaving the impurities as a separate solution or residue. </p>
