The invention relates to a method for separating uranium (VI) from one or several types of actinide selected from actinides (IV) and actinides (VI) other than uranium (VI), consisting a) in bringing into contact an organic phase which is insoluble in water and contains said uranium and one or several actinides with an acid aqueous solution containing at least a lacunar heteropolyanion and, if said actinide or one of said actinides is an actinide (VI), a reducing agent for selectively reducing said actinide (VI) and b) in separating the organic phase from the aqueous solution. Said invention can be used for reprocessing irradiated nuclear fuels and for processing rare-earth minerals, thorium and/or uranium.
L'invention a pour objet un procédé de séparation de l'uranium (VI) d'un ou plusieurs actinides choisis parmi les actinides (IV) et les actinides (VI) autres que l'uranium (VI), caractérisé en ce qu'il comprend les étapes suivantes a) mettre en contact une phase organique, non miscible à l'eau et contenant ledit uranium et ledit ou lesdits actinides, avec une solution aqueuse acide contenant au moins hétéropolyanion lacunaire et, si ledit actinide ou l'un au moins desdits actinides est un actinide (VI), un agent réducteur capable de réduire sélectivement cet actinide (VI) ; et b) séparer ladite phase organique de ladite solution aqueuse. Applications retraitement des combustibles nucléaires irradiés, traitement de minerais de terres rares, de thorium et/ou d'uranium.
