Abstract

METODO PARA RECUPERAR URANIO A PARTIR DE UN COPRECIPITADO DE SILICATO-URANIO POR LIXIVIACION DEL COPRECIPITADO.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE REDUCE EL PH DEL COPRECIPITADO A UN VALOR COMPRENDIDO ENTRE 2 Y 3; SEGUNDA, SE AÑADE UN LIXIVIADOR FORMADO POR UN ACIDO CAPAZ DE SOLUBILIZAR EL URANIO EN LA GAMA ESPECIFICADA DE PH, EN UNA RELACION PONDERAL DE COPRECIPITADO A LIXIVIADOR COMPRENDIDA ENTRE 1:1 Y 3:1; TERCERA, SE FILTRA LO ANTES POSIBLE LA SUSPENSION PROCEDENTE DE LA ETAPA ANTERIOR PARA SEPARAR EL LIXIVIADOR DEL COPRECIPITADOY LAVAR VARIAS VECES ESTE COPRECIPITADO PARA RECUPERAR LA MAXIMA CANTIDAD POSIBLE DE URANIO PRESENTE EN EL; Y POR ULTIMO, SE RECUPERA EL URANIO PRESENTE EN EL FILTRADO.
