Feb 05, 2013· The process continues with the actual refining of gold, to separate the impurities that are in it. There are different processes that could be used, including the Miller process and the Wohlwill process, both of which are highly effective in separating impurities and producing pure, high-grade gold.In the Miller Process, chlorine gas is bubbled into the molten gold. The impurities within the gold separate from it and form chlorides, which concentrate on the surface of the molten metal. It is then relatively easy to pour off the purified gold, which is about 99.5% pure.
