Abstract
Un proceso para la lixiviación de minerales que contienen sulfuros metálicos y uno o más metales preciosos o compuestos de metales preciosos, el proceso comprende los pasos de un primer paso de lixiviación para lixiviar los minerales en condiciones oxidativas a un pH menor de 4 para formar una lechada o pulpa, donde la suspensión o pulpa comprende una fase sólida que contiene componentes sin reaccionar, productos de reacción sólidos y azufre elemental, y someter la lechada o pulpa o residuo sólido del primer paso de lixiviación a un segundo paso de lixiviación que comprende lixiviación oxidativa a un pH de al menos 9,0 para formar de ese modo tiosulfato, por lo que el tiosulfato lixivia el metal precioso del residuo sólido.A process for the leaching of minerals containing metal sulphides and one or more precious metals or precious metal compounds, the process comprising the steps of a first leaching step to leach the minerals under oxidative conditions at a pH less than 4 to form a slurry or pulp, wherein the suspension or pulp comprises a solid phase containing unreacted components, solid reaction products and elemental sulfur, and subjecting the slurry or pulp or solid residue from the first leaching step to a second leaching step comprising leaching oxidatively at a pH of at least 9.0 to thereby form thiosulfate, whereby the thiosulfate leaches the precious metal from the solid residue.
