The station takes either a sample of gold or a large amount of it, and mixes it with soda, borax, lead or silver. Soda or borax help reduce the melting point of gold, and this facilitates the refining process. How is Gold Produced? Heating This mixture of gold and other additives is heated at a temperature of between 1000° C and 12000° C.
The two most popular gold refining techniques to extract pure gold include the Wohlwill process and the Miller process. The Miller process makes use of gaseous chlorine to pull out impurities during the gold's melting point. As a result, impurities come into the surface layer of the liquefied, purified gold.
