Electrolysis is widely used for Electroplating. Implementation of Electrolysis: In medieval times, aluminium was almost as precious as silver. Its extraction was not known and pure aluminium was extremely hard to come by. The application of electrolysis turned aluminium from a precious metal to one of the most largely used metals by humans.
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller 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.

Aug 07, 2017· But let's say the break even point would be on oz of gold per device. The concentration of gold in seawater is about 13 ug/m^3 (not 1.3 mg), so to extract one troy oz of gold you would have to process about 2.3 million M^3 of seawater. If the device could average 10 liters/second it would do that in about 7 years. That's a tall order.
