Gold Refining Techniques. 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.
