The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction thus, the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination, and the residue may then be treated by smelting to recover the balance

More gold is recovered by cyanidation than by any other process in cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution when gold dissolution is complete, the goldbearing solution is separated from the solids with ores of higher gold content greater than grams of gold per tonne of ore, cyanidation is accomplished by vat leaching, which involves holding a slurry of .
