Wohlwill process ore refining Britannica
In gold processing: Refining. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the casting functions as a positively charged electrode,.

2020-9-23 The Wohlwill process is another common process that can be used to purify metal ore with gold content into fine gold. Gold percentages on the Miller process are sometimes only 98 to 99 per cent pure in some industry locations, so occasionally industrial refining locations use the Miller process followed by the Wohlwill process.
