Abstract

1.- Un proceso para el tratamiento hidrometalúrgico de un mineral de níquel laterítico/cobalto que comprende una mezcla (2) de limonita y saprolita, caracterizado porque: - la mezcla (2) de limonita y saprolita se convierte en una pulpa (1) en la presencia de un agente de precipitación de hierro de manera tal que se forme una pulpa inicial que tiene un contenido de sólidos de entre el 10% y el 40% en peso, preferentemente de entre el 20% y el 30%; - la pulpa de limonita y saprolita inicial pasa por un proceso de lixiviación (4) con ácido sulfúrico (5) a una temperatura de entre 70°C y el punto de ebullición de la solución, preferentemente entre 40°C y el punto de ebullición, a presión atmosférica; - la pulpa obtenida mediante el proceso de lixiviación (4) optativamente pasa por un proceso de neutralización (7) de manera tal que tenga un pH de entre 2 y 3; - y se realiza un proceso de separación de sólido y líquido (8) en dicha pulpa, preferentemente mediante la decantación y el lavado contra la corriente o la filtración, de manera tal que se obtenga un residuo sólido (9) , que está principalmente en forma de jarosita, y una solución que contiene iones de níquel y cobalto.2.- Un proceso de acuerdo con la reivindicación 1, caracterizado porque la relación de saprolita/limonita de la mezcla (2) es entre 0, 5 y 3.3.- Un proceso de acuerdo con la reivindicación 1 o la reivindicación 2, caracterizado porque el tiempo de retención de la pulpa durante el proceso de lixiviación (4) con ácido sulfúrico es entre 1 y 24 horas, preferentemente de 6 horas a 12 horas.
