Abstract

Recuperacion de metal precioso por lixiviacion con tiosulfato donde se genera in situ un lixiviante de tiosulfato empleando azufre elemental generado por la oxidacion parcial de una alimentacion sulfurosa que contiene metal precioso y/o empleando reactivos provenientes de los efluentes del proceso. Reivindicacion 1: Un proceso para recuperar metal precioso de un material sulfuroso que contiene metal precioso caracterizado porque comprende los pasos de: formar una lechada sulfurosa acuosa que contiene metal precioso que comprende el material sulfuroso que contiene metal precioso; someter la lechada sulfurosa que contiene metal precioso a una oxidacion parcial para producir una lechada oxidada que contiene metal precioso que contiene azufre elemental; neutralizar la lechada oxidada que contiene metal precioso que contiene azufre elemental; formar compuestos de tiosulfato en la lechada oxidada que contiene metal precioso haciendo reaccionar el azufre elemental proveniente de la oxidacion parcial con un reactivo que reacciona con azufre elemental para formar compuestos de tiosulfato para una lechada que contiene metal precioso que contiene un lixiviante a base de tiosulfato; lixiviar metal precioso de la lechada que contiene metal precioso para producir una lechada lixiviada que compende un residuo solido y lixiviado que contiene metal precioso; y recuperar metal precioso del lixiviado que contiene metal precioso.
