Processing, smelting and refining gold World Gold Council

The Miller process is rapid and simple, but it produces gold of only about 995 percent purity The Wohlwill process increases purity to about 9999 percent by electrolysis In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride...

Wohlwill process

The Wohlwill process is necessary for highest purity gold applications, and when lower purity gold is required refiners often utilize the Miller process due to its relative ease, quicker turnaround times, and because it does not require a large inventory of gold, in this case gold chloride, on site at all tim A variant of the Wohlwill process is the fizzer cell...
