Title (EN) RECOVERY OF URANIUM
(FR) RÉCUPÉRATION D'URANIUM
Abstract:
(EN) A process is provided for recovering uranium comprising (A) bringing a solution (A) into contact with a resin (A) to produce a mixture of solution (B) and resin (B), wherein the solution (A) is an aqueous solution comprising dissolved sodium carbonate, sodium bicarbonate, or a mixture thereof, and wherein the resin (A) is a strong acid cation exchange resin that comprises one or more cationic moiety that comprises uranium and one or more cationic moiety that comprises iron, and (B) separating the solution (B) from the resin (B).
(FR) L'invention concerne un procédé de récupération d'uranium consistant (A) à mettre en contact une solution (A) avec une résine (A) pour produire un mélange de solution (B) et de résine (B), la solution (A) étant une solution aqueuse comprenant du carbonate de sodium, du bicarbonate de sodium dissous ou un mélange associé, et la résine (A) étant une résine échangeuse de cation de type acide fort qui comprend une ou plusieurs fraction cationique qui comprend de l'uranium et une ou plusieurs fraction cationique qui comprend du fer, et (B) à séparer la solution (B) de la résine (B).
