gold ore processing decantation tanks

Introduction to Cyanide Gold Mining

Types of Gold Ore Deposits SedimentHosted Disseminated Gold, Volcanic water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through dewatering the mine, from the embankment underdrains and decantation
