How to Purify Gold | Sciencing

GCM

The value of gold depends in part on its purity. There are several useful methods to purify gold, including the Wohlwill process, the Miller process, cupellation and acid treatment. In 1874, Dr. Emil Wohlwill of the Norddeutsche Affinerie in Hamburg, Germany, developed a method to purify gold through electrolysis.Read more

Processing, smelting and refining gold | World Gold Council

GCM

The Miller 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. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.Read more

Gold Electrolysis Process & Gold Recovery

GCM

Fill hydrogen peroxide H 2 O 2 40ml per 2000 ml melted gold chemical water. stir it together and wait for 5 minutes. You have to fill hydrogen peroxide H 2 O 2 in melted gold chemical water to destroy cyanide chemical structure. So, it is not fully element. It cannot melt gold. If we do not fill hydrogen peroxide H 2 O 2 That makes the next step gold piece melted and change into solution.Read more
