The electric current causes a forced oxidation-reduction reaction. Electrolysis is an integral part of electrometallurgy, and highly pure elements can be produced using this process. Generally, all mining operations require the ore to be beneficiated (treating a raw material to improve its properties).

Aug 07, 2017· But why all the emphasis on gold? There are other valuable metals in seawater. From the same amount of water needed to produce one oz of gold you could extract 21,500 oz of silver, worth 200 times more than an oz of gold. A silver extraction device operating at a much more reasonable 0.5 liters/second would break even in about 1.5 years.
