The Miller Process for Refining Gold - Gold, Mining

2012-2-9  Unlike the Wolhwill Process described earlier in this series the Miller Process doesn’t use electricity but rather uses a stream of chlorine gas that is passed through a crucible of molten gold that produces gold that is 99.95 Fine. It works to remove all the impurities because gold is least affected by chlorine so all the other impurities are removed as chloride slag floating on the surface of the molten gold
