Gold parting

The Miller process affords gold up to 99.5% purity. The process involves blowing a stream of chlorine through molten gold. Impurities in the gold form chlorides, which form a slag that floats on the molten gold. [2] [3] Invented by Emil Wohlwill in 1874, the Wohlwill process produces the highest purity gold (99.999%).
