Abstract
Se proporcionan procesos para la recuperación de metales preciosos de materiales refractarios utilizando materiales que utilizan lixiviantes de tiosulfato. Los procesos pueden emplear lixiviantes que incluyen en mayoría solamente cantidades pequeñas de cobre y/o amoniaco y operan a un pH relativamente bajo; la reducción de politionatos, atmósferas inertes para controlar la producción de politionato, y soluciones electrolíticas que proporcionan velocidades relativamente elevadas de recuperación del metal precioso.
