Abstract

PROCEDE PERFECTIONNE DE RECUPERATION DE L'URANIUM VI CONTENU DANS UN ACIDE PHOSPHORIQUE IMPUR PAR EXTRACTION LIQUIDE-LIQUIDE. IL COMPREND DANS UN PREMIER CYCLE LE TRAITEMENT DE L'ACIDE IMPUR PAR UNE PREMIERE PHASE ORGANIQUE EXTRACTIVE ET LA REGENERATION DE L'URANIUM PAR UNE SOLUTION PHOSPHORIQUE CONTENANT DES IONS FER II; DANS UN DEUXIEME CYCLE, LE TRAITEMENT DE LA SOLUTION PHOSPHORIQUE, APRES OXYDATION, PAR UNE DEUXIEME PHASE ORGANIQUE EXTRACTIVE PUIS LE TRAITEMENT DE CETTE PHASE POUR EN RECUPERER L'URANIUM, LE PERFECTIONNEMENT COMPRENANT LE LAVAGE DE LA DEUXIEME PHASE ORGANIQUE CHARGEE EN URANIUM AU MOYEN D'UNE SOLUTION AQUEUSE PHOSPHORIQUE EXEMPTE DE FER OBTENUE PAR LAVAGE AQUEUX DE LA PHASE ORGANIQUE DU PREMIER CYCLE AVANT REGENERATION DE L'URANIUM ET APRES L'AVOIR CONCENTREE. APPLICATION A LA RECUPERATION DE L'URANIUM VI CONTENU DANS UN ACIDE PHOSPHORIQUE DE VOIE HUMIDE.
