A pyrometallurgical chlorination process, the Miller process is one of the oldest and most widely used processes in large scale . It involves bubbling chlorine gas through molten bullion. The base metals and silver are removed as chlorides, which either volatilize or form a molten slag on the surface of the melt.

04.12.2020Gold Refining Techniques The two most popular 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.
