Abstract

PROCESO ESPECIALMENTE UTIL PARA SEPARAR MAGNETICAMENTE PUREZAS ATRAIBLES DE BARROS ACUOSOS O SUSPENSIONES, QUE INCLUYE EL PASAR LA SUSPENSION (42) A TRAVES DE UNA MATRIZ POROSA FERROMAGNETICA AL TIEMPO QUE SE APLICA UN CAMPO MAGNETICO A DICHA MATRIZ (10), SOBRE LA QUE SE RECOGEN LAS IMPUREZAS, Y REGENERAR A CONTINUACION LA MATRIZ LIMPIANDO LAS IMPUREZAS RECOGIDAS CON UN LIQUIDO DE ARRASTRE (26), POR EJEMPLO AGUA. EL PERFECCIONAMIENTO CONSISTE EN, TRAS DETENER EL PASO DE LA SUSPENSION POR LA MATRIZ, PERO ANTES DE UTILIZAR EL LIQUIDO DE ARRASTRE, INTRODUCIR GAS A PRESION (68), POR EJEMPLO AIRE COMPRIMIDO, EN EL SEPARADOR PARA DESPLAZAR LA SUSPENSION ALLI RETENIDA, Y RECUPERAR LA SUSPENSION DESPLAZADA. ADEMAS, EL LIQUIDO DE LAVADO QUE QUEDA EN LA MATRIZ TRAS EL ARRASTRE PUEDE SER DESPLAZADO DE ELLA UTILIZANDO AIRE COMPRIMIDO. AL DESPLAZAR DE LA MATRIZ LA SUSPENSION RETENIDA CON GAS COMPRIMIDO EN LUGAR DE LIQUIDO DE ARRASTRE, DICHA SUSPENSION NO SE DILUYE, PUDIENDO RECUPERARSE EN LUGAR DE SER ELIMINADA COMO EN LOS PROCESOS ANTIGUOS.
