Abstract

PROCEDE PERMETTANT DE CONCENTRER UNE MATIERE CONTENANT DE L'URANIUM ET DU CALCIUM EN SOLUTION. ON FAIT PASSER CETTE SOLUTION A TRAVERS UN PREMIER SYSTEME DE SEPARATION CONTENANT AU MOINS UNE MEMBRANE SEMI-PERMEABLE CAPABLE DE CONCENTRER L'URANIUM AFIN DE CONCENTRER CET URANIUM ET DE LAISSER PASSER UNE IMPORTANTE PARTIE DE LA SOLUTION EN DONNANT UN COURANT ENRICHI EN URANIUM ET UN COURANT APPAUVRI EN URANIUM, CONTENANT DES CATIONS, ANIONS ET IMPURETES DE BAS POIDS MOLECULAIRE. ON PEUT AINSI CONCENTRER DE PETITES QUANTITES D'URANIUM PRESENT DANS DES SOLUTIONS DE LIXIVIATION ENRICHIES, TOUT EN MAINTENANT LA SOLUTION INITIALE DE LIXIVIATION PRETE A ETRE RECYCLEE DANS LE GITE SOUTERRAIN.
