PROCEDIMIENTO PARA LA RECUPERACIÓN DE NÍQUEL Y COBALTO A PARTIR DE MINERALES LATERÍTICOS MEDIANTE LA LIXIVIACIÓN EN SERIE A PRESIÓN ATMOSFÉRICA
Main Article Content
Abstract
La presente invención establece un método para la recuperación de níquel y de cobalto de minerales lateríticos con alto contenido de Mg mediante un esquema de percolación en serie donde el mineral es lixiviado a presión atmosférica mediante el uso de un licor residual del proceso ácido a presión (HPAL), el licor residual con adición de ácido sulfúrico, o soluciones diluidas de ácido sulfúrico se obtienen recuperaciones de más de 80% de Ni y de Co y soluciones con contenidos de 1-5 g/l Ni y 0.1-0.5 g/l de Co, sin contenido de ácido libre (pH=2,5-3,5) y bajo contenido de hierro.
