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 and solvent in large tanks equipped with agitators.
