Abstract

L'invention concerne un nouveau procédé pour la récupération de l'uranium contenu dans des solutions phosphatées. Ce procédé comprend notamment une étape de mise en contact de la solution phosphatée uranifère avec une phase organique contenant un diester de l'acide pyrophosphorique; une étape de mise en contact de cette phase organique avec une solution alcaline; une étape d'addition à la solution alcaline d'un agent de précipitation de l'uranium; une séparation de la phase organique d'avec la phase aqueuse et un recyclage de la phase organique vers la première étape de mise en contact Application à la production directe d'un oxyde d'uranium.
