Gold Smelting & Refining Process

The Aqua Regia Process is appropriate to be employed in small scale and the metallic gold to be obtained is as pure as 99.9%. The main steps of the process are to dissolve the precious metals and some impurities. Since the Aqua Regia is a mixture between nitric acid and hydrochloric acid, part of the silver will remain in solution and other part will form a silver chloride precipitate. Then ...
