Abstract

PROCEDIMIENTO PARA LIXIVIAR UN METAL VALIOSO DESDE MATERIALES OXIDADOS, TALES COMO MINERAL LATERITICO DE NIQUEL QUE COMPRENDE EL PASO DE LIXIVIAR EL MINERAL CON UN LIXIVIADOR QUE COMPRENDE UNA SAL CATIONICA Y ACIDO HIDROCLORICO. PUEDE AGREGARSE UN OXIDANTE O CLORURO METALICO ADICIONAL COMO EL QUE RESULTA DE LA OPERACION DE LIXIVIACION. EN UNA MODALIDAD, EL PROCESO COMPRENDE LA RECUPERACION DEL METAL VALIOSO DESDE EL MATERIAL, COMPRENDIENDO LOS PASOS DE LIXIVIAR EL MINERAL CON UN LIXIVIADOR, SEPARAR EL PERCOLADO RICO EN METAL VALIOSO DESDE EL MINERAL EN UNA PRIMERA SEPARACION SOLIDO/LIQUIDO, OXIDAR Y NEUTRALIZAR AL PERCOLADO RICO EN METAL VALIOSO ASI OBTENIDO, Y SEPARAR UNA SOLUCION DE CLORURO DE MAGNESIO DESDE EL PERCOLADO ASI OBTENIDO EN UNA SEGUNDA SEPARACION SOLIDO/LIQUIDO. EN OTRA MODALIDAD, LA SOLUCION LIXIVIADORA SE REGENERA DESDE LA SOLUCION CLORURO DE MAGNESIO. EN UNA MODALIDAD ADICIONAL, LA REGENERACION DE LA SOLUCION LIXIVIADORA INCLUYE EL PASO DE PRODUCIR OXIDO DE MAGNESIO DESDE LA SOLUCION DE CLORURO DE MAGNESIO.
