Gold Smelting & Refining Process

Gold-Silver Separation. The initial step is to weight the Dore metal. Since silver is leached by nitric acid and gold no, the next step is to attack the Dore metal with a hot diluted solution of nitric acid. The acid dissolves the silver and leaves the gold that has to be rinsed, dry, and weight on a scale of high sensibility such as 0.001 mg.
