How to Purify Gold | Sciencing
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
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
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
Electrowinning - Wikipedia
Electrowinning is the oldest industrial electrolytic process. The English chemist Humphry Davy obtained sodium metal in elemental form for the first time in 1807 by the electrolysis of molten sodium hydroxide.. Electrorefining of copper was first demonstrated experimentally by Maximilian, Duke of Leuchtenberg in …Read more
Gold processing | Britannica
Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms ...Read more
