Abstract

La presente se relaciona con un método para la recuperacion de oro a partir de un producto intermedio o residuo que contiene hierro y azufre generado en la lixiviacion de una materia prima de cobre relacionado con la produccion hidrometalurgica de cobre. La recuperacion tanto del cobre como del oro tienen lugar en un ambiente de cloruro. El oro contenido en el producto intermedio o residuo es lixiviado con cobre divalente y cloro en una solucion de cobre (II) cloruro-cloruro de sodio, en condiciones donde el potencial de reduccion de oxidacion fluctua entre los 650-750 mV y el pH oscila entre 1-1.6. el ácido generado durante la alimentacion de cloro se neutraliza con el oxicloruro de cobre (II) generado en el proceso.This is related to a method for recovering gold from an intermediate product or residue containing iron and sulfur generated in the leaching of a copper raw material related to the hydrometallurgical production of copper. The recovery of both copper and gold takes place in a chloride environment. The gold contained in the intermediate product or residue is leached with divalent copper and chlorine in a solution of copper (II) chloride-sodium chloride, in conditions where the oxidation reduction potential fluctuates between 650-750 mV and the pH ranges between 1-1.6. The acid generated during the chlorine feed is neutralized with the copper (II) oxychloride generated in the process.
