Abstract

Se describe un método para recuperar hierro de una solución de sulfato de zinc de acuerdo con una modalidad de la presente descripción se asocia con la recuperación de hierro de una solución de sulfato de zinc producida por un proceso de lixiviación en la cual el mineral de zinc se disuelve en ácido sulfúrico. El método comprende un proceso de acondicionamiento que incluye un paso para reducir una solución de entrada de proceso de acondicionamiento, que es la solución de sulfato de zinc, y un proceso de precipitación de hierro para recuperar hierro como hematita, incluyendo un paso para presurizar y oxidar una solución de entrada de proceso de precipitación de hierro descargada del proceso de acondicionamiento. El proceso de precipitación de hierro se lleva a cabo en una temperatura que varía de 135°C a 150°C y una presión que varía de 5 barg a 10 barg. Además, un método para recuperar hierro de una solución de sulfato de zinc de acuerdo con una modalidad de la presente descripción se asocia con la recuperación de hierro de una solución de sulfato de zinc producida por un proceso de lixiviación en la cual el mineral de zinc se disuelve en ácido sulfúrico. El método comprende un proceso de acondicionamiento que incluye un paso para reducir una solución de entrada de proceso de acondicionamiento, que es la solución de sulfato de zinc, y un proceso de precipitación de hierro para recuperar hierro como hematita, incluyendo un paso para presurizar y oxidar una solución de entrada de proceso de precipitación de hierro descargada del proceso de acondicionamiento. La solución de entrada de proceso de precipitación de hierro tiene un potencial de oxidación-reducción de -100 mV o menos cuando se utiliza un electrodo de plata/cloruro de plata (Ag/AgCI) como un electrodo de referencia.
