Abstract
Un método para la recuperación de cobre en el cual el mineral sulfuro de cobre se somete a un ciclo de lixiviado con cloruro y luego a un ciclo de biolixiviado, en el cual el mineral se calienta con una solución que contiene cloruro del lixiviado con cloruro.Reivindicación 1: Un método para recuperar cobre de una mena que contiene mineral de sulfuro de cobre, caracterizado porque el método incluye los pasos de tratar la mena en a) un ciclo de lixiviado con cloruro en el cual la concentración de cloruro se mantiene entre 7 g/l y 80 g/l; y (b) un ciclo de biolixiviado en el cual (b(i)) la mena se trata con una solución con alto contenido de cloruro del ciclo de lixiviado con cloruro; (b(ii)) las impurezas asociadas con el ciclo de lixiviado con cloruro se eliminan; y (b(iii)) la mena se irriga con una solución microbiana adecuada con una concentración de cloro menor de 6 g/l.A method for the recovery of copper in which the copper sulphide mineral is subjected to a cycle of chloride leaching and then a cycle of biolixing, in which the mineral is heated with a solution containing chloride of chloride leaching. Claim 1: A method for recovering copper from a ore containing copper sulphide ore, characterized in that the method includes the steps of treating the ore in a) a chloride leaching cycle in which the chloride concentration is maintained between 7 g / l and 80 g / l; and (b) a bioleaching cycle in which (b (i)) the ore is treated with a high chloride solution of the chloride leaching cycle; (b (ii)) impurities associated with the chloride leaching cycle are removed; and (b (iii)) the ore is irrigated with a suitable microbial solution with a chlorine concentration of less than 6 g / l.
