Abstract

Se proporcionan procesos para la recuperacion de metales preciosos de materiales refractarios utilizando materiales que utilizan lixiviantes de tiosulfato. Los procesos pueden emplear lixiviantes que incluyen en mayoria solamente cantidades pequenas de cobre y/o amoniaco y operan a un pH relativamente bajo, la reduccion de politionatos, atmosferas inertes para controlar la produccion de politionato, y soluciones electroliticas que proporcionan velocidades relativamente elevadas de recuperacion del metal precioso.
