Abstract

Se proporcionan procesos para recuperar metales preciosos a partir de materiales refractarios utilizando lixiviantes de tiosulfato. Los procesos pueden emplear lixiviantes que incluyan cuando mucho solamente pequenas cantidades de cobre y/o amoníaco, y operan a un pH relativamente bajo, reduccion de politionatos, atmosferas inertes para controlar la produccion de politionato, y soluciones electrolíticas que proporcionan velocidades relativamente altas de recuperacion del metal precioso.
