Abstract

L'invention concerne un procédé de séparation du fer à partir d'une phase organique liquide initiale contenant de l'uranium, et du fer, dans lequel on met en contact la phase organique liquide initiale avec une solution aqueuse dite solution aqueuse de déferrisation, moyennant quoi le fer passe dans la solution aqueuse pour former une phase aqueuse liquide finale, et l'uranium reste dans la phase organique liquide initiale pour former une phase organique liquide finale dite phase organique déferrisée; ledit procédé étant caractérisé en ce que la solution aqueuse de déferrisation contient un acide inorganique et de l'uranium, et ne contient pas de fer. L'invention concerne, en outre, un procédé d'extraction de l'uranium à partir d'une solution aqueuse d'un acide inorganique contenant de l'uranium et du fer.The invention relates to a process for separating iron from an initial liquid organic phase containing uranium, and iron, in which the initial liquid organic phase is brought into contact with an aqueous solution called an aqueous deferrisation solution, whereby the iron passes into the aqueous solution to form a final aqueous liquid phase, and the uranium remains in the initial liquid organic phase to form a final liquid organic phase called de-ironed organic phase; said method being characterized in that the aqueous deferrisation solution contains an inorganic acid and uranium, and does not contain iron. The invention further relates to a process for extracting uranium from an aqueous solution of an inorganic acid containing uranium and iron.
