In cyanidation,metallic goldis oxidised and dissolved in an alkaline cyanide solution. Whengold dissolutionis complete, the gold-bearing solution is separated from the solids. With ores of highergold content(greater than 20 grams ofgoldper tonne ofore), cyanidation is accomplished by vat leaching, which involves holding a slurry oforeand solvent in large tanks equipped with agitators.
