Abstract

Un proceso para lixiviar minerales que contienen sulfuros de metal y uno o mas metales preciosos o compuestos de metales preciosos, el proceso que comprende los pasos de un primer paso de lixiviacion para lixiviar los minerales en condiciones oxidativas a un pH de menos de 4 para formar una suspension espesa o pulpa, la suspension espesa o pulpa que comprende una fase solida que contiene componentes sin reaccionar, productos de reaccion solidos y azufre elemental, y someter la suspension espesa o pulpa o residuo solido del primer paso de lixiviacion a un segundo paso de lixiviacion que comprende lixiviacion oxidativa a un pH de al menos 9.0 para formar de esta manera tiosulfato, por lo que el tiosulfato lixivia metales preciosos del residuo solido.
