Electrowinning For Gold Mining - Blogger

Metals most often processed in electrowinning techniques are copper, gold, and silver. Most metals occur in nature in the form of oxidized ore and thus should be reduced to form a pure metal. Ore is dissolved into some preprocessing in aqueous electrolyte or in the molten salt and the resulting solution is electrolysis.

Gold from sea water (new technique) - Creativity Pool Forums

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.
