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, Read More

Feb 07, 2017· Hans Emil Wohlwill, a German engineer, invented the Wohlwill Process in 1874. Unlike the Miller Process, which is known among refineries as a relatively cheap and easy way to produce high-purity gold (in the 99.95% purity range), the Wohlwill Process is complex and expensive.But when done correctly, it can produce gold samples of 99.999% purity.
