The main processing steps of the Precious Metals Operations are the smelter, the copper leaching and electrowinning plant and the precious metals refinery. The operations are designed in such a way that raw materials can enter the flowsheet at the most optimal process step, determined by their physical aspect, their analytical fingerprint and ...
How is Gold Made UCSB Science Line. Wohlwill process The electrolytic method of gold refining was first developed by Dr. Emil Wohlwill of Norddeutsche Affinerie in Hamburg in 1874. Dr. 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 Refining Process. Refiners start with one of two types of gold: a doré bar or scrap. Doré bars are produced by miners and are about 80 percent pure. Refiners increase the purity by separating the other precious metals and less precious metals that are mined with it. Using induction heating, doré bars and scrap are turned into molten metal.
A refinery's processing flow scheme is largely determined by the composition of the crude oil feedstock and the chosen slate of petroleum products. The example refinery flow scheme presented in Figure shows the general processing arrangement used by refineries in the United States for major refinery processes.
