refining gold process with washing machine for slag removal

Melting and Refining of Gold

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.
