Abstract

Se divulga un método para producir un sulfato de níquel de grado de batería mediante mineral de níquel laterítico. El método comprende los siguientes pasos el mineral de níquel laterítico se clasifica para obtener un mineral en trozos y un mineral de lodo y arena; el mineral en trozos se tritura y se somete a un tratamiento de lixiviación en vertedero para obtener una solución bruta de sulfato de níquel A; el mineral de fango y arena se separa para obtener un mineral con alto contenido en cromo, un mineral con bajo contenido en hierro y alto contenido en magnesio, y un mineral con alto contenido en hierro y bajo contenido en magnesio, y el mineral con bajo contenido en hierro y alto contenido en magnesio se seca, calcina, reduce y sulfura para obtener una mata con bajo contenido en níquel; la mata de bajo contenido en níquel se somete a soplado, extracción de agua y, a continuación, lixiviación a presión con oxígeno para obtener una solución B de sulfato de níquel en bruto; el mineral con alto contenido en hierro y bajo contenido en magnesio se somete a lixiviación a presión para obtener una solución C de sulfato de níquel en bruto; y las soluciones A, B y C de sulfato de níquel en bruto se extraen y, a continuación, se someten a cristalización por evaporación para obtener un sulfato de níquel de grado batería. En la presente invención se aprovechan plenamente las ventajas del proceso RKEF, del proceso de lixiviación a presión y del proceso de lixiviación en vertedero, y se integran para complementarse mutuamente. Se aprovechan las características de los diferentes minerales, se utilizan procesos adecuados para el tratamiento, el coste de producción es bajo y la tasa de recuperación integral de níquel y cobalto es del 90% o superior.
