Vat leaching is carried out in vats ranging in capacity from 30 to tons Sand for leaching is separated from slime in cones V boxes classifiers and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore As a rule leaching is a simple process involving a vat of well mixed neutralized sand ample contact with strong and weak preparation prior to leaching Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen There are three general methods of contacting ores with leach solutions 1 heap leaching 2 vat leaching and 3 agitation leaching Cyanidation heap leaching and vat leaching account for most gold and silver recovery
