The Gold Smelting Process - Melting, Smelting & Refining,
Jan 18, 2017· Many people confuse gold smelting with melting. Whereas gold melting is simply heating gold to turn into a liquid form before forming gold bars, smelting is a more complex process that involves the removal of impurities from gold using heat, pressure and a number of chemicals.
