Abstract

L'invention concerne un procédé de récupération et de concentration de l'uranium VI contenu dans une phase organique. On traite en continu la phase organique dans une zone de contact, au moyen d'une solution aqueuse complexante de l'uranium IV contenant un agent oxydo-réducteur à l'état réduit, la solution aqueuse provenant en totalité ou en partie du compartiment cathodique d'une cellule électrolytique à séparateur, sous tension de courant continu. La phase aqueuse sortant de la zone de contact alimente en totalité ou en partie le compartiment anodique de la cellule électrolytique. Application à la recupération et à la concentration de l'uranium contenu dans un acide phosphorique de voie humide.
