Abstract

Se describe un procedimiento de biolixiviacion y extraccion por disolventes con recuperacion selectiva de cobre y zinc a partir de concentrados polimetalicos de sulfuros, que comprende un proceso de biolixiviacion y reduccion de ion ferrico y un proceso de extraccion por disolventes de cobre y zinc. El proceso de biolixiviacion y reduccion de ion ferrico comprende una etapa de acondicionamiento de una pulpa de concentrados; una etapa de biolixiviacion, en donde la pulpa un vez acondicionada se somete a un proceso de biolixiviacion empleando una pluralidad de biorreactores del tipo de tanque agitado con un sistema para inyeccion y difusion de aire, lo que permite manejar una densidad de pulpa mayor al 15%; una etapa de separacion de solidos de una solucion rica en iones metalicos proveniente de la etapa de biolixiviacion; y, una etapa de reduccion de ion ferrico, en donde la pulpa proveniente de la etapa previa se somete a un etapa de transformacion de los iones ferricos a iones ferrosos. La etapa de extraccion por disolventes comprende una etapa de extraccion por disolventes y electrolisis de cobre; una etapa de control de arsenico, en donde a la solucion una vez que se le ha extraido el cobre, se le controla el arsenico; y, una etapa de extraccion por disolventes y electrolisis de zinc, que emplea una disolucion extractora de zinc a base de acidos fosfinicos
