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.
