Gold Chlorides: Naturally Concentrating the King of Metals

But, there is a natural process involving chlorine that concentrates gold under volcanoes and forms deposits that are worth the expense of mining. The compounds gold chloride (AuCl) and hydrogen gold chloride (HAuCl 2) play important natural roles in making gold accessible to us. Steamed out of Magma.

Miller process Wikipedia

The Miller process is an industrialscale chemical procedure used to refine gold to a high degree of purity (99.95%). It was invented by Francis Bowyer Miller ( patented 1867). This chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold.

"Gold chlorination" by Edwin Thompson Perkins

"In a process of gold chlorination recently introduced and apparently used with success in Southern Australia, potassium permanganate, common salt and sulphuric acid were used as the generators of the chlorine. A series of experiments was made to determine the efficisacy of these reagents and for developing chlorine as compared with other methods in use"page 1.
