Abstract

Un proceso para la extracción de cobre de una mina o concentrado de sulfato de cobre, que comprende los siguientes pasos: someter la mina o concentrado a la oxidación a presión en la presencia de oxígeno y en una solución de ácido clorhidrico para obtener un resultado de filtrado de oxidación a presión y una sal básica insoluble de sulfato de cobre, caracterizada en la oxidación a presión es realizada en presencia de una fuente de iones de bisulfato o sulfato que ha sido seleccionado del grupo que consiste en ácido sulfúrico y un sulfato metálico que se hidroliza en la solución acídica y donde la cantidad de la fuente de iones de bisulfato o sulfato que es añadida contiene por lo menos la cantidad estequiométrica de iones de sulfato o bisulfato necesarios para producir la sal básica de sulfato de cobre menos la cantidad de sulfato generado in situ en la oxidación a presión.A process for the extraction of copper from a copper sulfate mine or concentrate, comprising the following steps: subjecting the mine or concentrate to oxidation under pressure in the presence of oxygen and in a solution of hydrochloric acid to obtain a result of pressure oxidation filtering and an insoluble basic copper sulfate salt, characterized in pressure oxidation, is performed in the presence of a source of bisulfate or sulfate ions that has been selected from the group consisting of sulfuric acid and a metal sulfate that hydrolyzes in the acidic solution and where the amount of the bisulfate or sulfate ion source that is added contains at least the stoichiometric amount of sulfate or bisulfate ions necessary to produce the basic salt of copper sulfate minus the amount of sulfate generated in situ by pressure oxidation.
