Abstract

L'invention se rapporte à un procédé de récupération des terres rares et de l'uranium(vi) présents dans une solution aqueuse d'acide phosphorique par extraction liquide-liquide qui permet, non seulement de co-extraire très efficacement les terres rares et l'uranium(vi) de cette solution aqueuse, mais aussi de récupérer ensuite sélectivement 5 les terres rares d'une part, et l'uranium(vi) d'autre part. Applications : traitement de solutions aqueuses issues de la lixiviation de phosphates naturels par l'acide sulfurique en vue de valoriser les terres rares et l'uranium(vi) présents dans ces solutions aqueuses.The invention relates to a process for recovering rare earths and uranium(vi) present in an aqueous solution of phosphoric acid by liquid-liquid extraction which not only makes it possible to very efficiently co-extract rare earths and the uranium(vi) from this aqueous solution, but also to then selectively recover 5 the rare earths on the one hand, and the uranium(vi) on the other hand. Applications: treatment of aqueous solutions resulting from the leaching of natural phosphates with sulfuric acid with a view to valorizing the rare earths and uranium(vi) present in these aqueous solutions.
