What Is Smelting? Many people confuse gold smelting and melting. While melting entails heating the gold from solid to liquid form before forming gold bars, the smelting process is more complex and involves removing impurities from the gold using a combination of pressure, heat, and several chemicals.
Gold refining can be achieved by high-temperature chlorination of the molten metal (Miller process) followed by electrorefining (Wohwill pro cess). The Miller process consists of chlorine injection into the molten bullion by means of an immersed clay tube. This process has three stages: 1.

The cuprous oxide is dissolved in the metal, and so carries oxygen to all parts of the molten mass. The process is efficacious, but the gold is, of course, contaminated with the reduced copper. The use of manganese dioxide in the Transvaal in refining gold-zinc-slimes from the cyanide process was described by Johnson and Caldecott in 1902.
