Abstract
La presente invención se relaciona con un método para recobrar níquel a partir de mineral laterítico, con alto contenido de magnesio, el cual además contiene hierro. Los minerales referidos como minerales saprolíticos son sometidos a lavado mediante drenaje con un ácido mineral, a partir de un grupo consistente de ácido clorhídrico (HCl), sulfúrico (H2SO4) ó nítrico (HNO3), siendo en HCl el preferido. Siguiendo el lavado con drenaje, empleando HCl, la solución impregnada obtenida es separada a partir de los sólidos no disueltos y el níquel es preferentemente recobrado mediante el contacto de dicha solución con una resina selectiva para la absorción del níquel. El refinado restante que contiene cloruros de hierro y magnesio puede ser sometido a pirohidrólisis para producir sus respectivos óxidos y HCl libre reciclarlos en el sistema de lavado. El níquel es extraído a partir de la resina usando una solución de separación de dicho ácido y el níquel es posteriormente extraído a partir de la solución de separación cargada de níquel.
