The Miller process is one of the most used in the gold refining. In this process the charge is melted in the induction furnace. Chlorine gas is introduced into the molten raw gold through a rotating lance in a very precise and controlled way, so that no break through of chlorine gas occurs.

The gold content is captured in a 'mud bag' around the anode. It is washed and dried, then melted and refined in a chlorination process where chlorine gas is introduced into the melting crucible. Gold is separated from the remaining base metals and is poured into granules or bars for commercial sale.
