Abstract

Un proceso para la extracción de cobre a partir de una meno o concentrado de cobre sulfuroso, el cual comprende las siguientes etapas: Someter la mena o concentrado o ilxivlación por agitación a temperatura y presión elevadas, para obtener un líquido resultante de ilxiviación ácido, el cual contiene el cobre disuelto; y reducir la acidez del líquido resultante de ilxiviación ácida efectuando la ilxiviación por percolación de un lecho de mena de cobre o roca granulada de bajo grado, con dicho líquido resultante de lixiviación ácida, con lo cual se eleva el pH del líquido de ilxiviación.
