Processing, smelting and refining gold World Gold Council

In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore

Electrowinning an overview ScienceDirect Topics

At the beginning of the plating cycle when the gold solution tenors are high, maximum current is needed to plate the gold. As the gold plates, with removal from the solution phase, the cell resistance will rise and the current will fall. This is in keeping with the need to plate gold at a slower rate in the latter part of the plating cycle.
