The process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold. The process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.Leave Us Now

The Wohlwill increases purity to about 99.99 percent by electrolysis. In this , a casting of impure is lowered into an electrolyte solution of hydrochloric acid and chloride. Under the influence of an electric current, the casting functions as a positively charged electrode, or anode.
