Wohlwill process Wikipedia

The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). The process was invented in 1874 by Emil Wohlwill. This electrochemical process involves using a cast gold ingot, often called a Doré bar, of 95%+ gold to serve as an anode.

ABC Refinery ATO abcrefineryato

Gold refining techniques include the aqua regis process, fizzer cell, Wohlwill process, Miller process, cupellation and more. The most popular method used is the Miller method, but it’s not the most popular method for ABC Refinery ATO. The Miller process may be the easiest to utilize but it produces gold around a 99.5 percent purity.

Wohlwill's process is based on the solubility of gold, but the insolubility of silver, in an electrolyte solution of gold chloride (AuCl 3) in hydrochloric acid. The impure gold is cast into anodes of about 100 ounces each, which are suspended in porcelain cells, while the cathodes are thin strips of pure gold.
