Abstract
L'invention est relative à un procédé de récupération d'uranium au départ de solutions d'acide phosphorique. Procédé de récupération d'uranium au départ d'une solution d'acide phosphorique issue d'un procédé par voie humide et dérivant de l'acidification de minerais de phosphates uranifères, dans lequel l'uranium est réduit à la forme uraneuse, transféré à une phase organique par un procédé d'échange d'ions, épuisé à partir de la phase organique et oxydé, de préférence en utilisant du peroxyde d'hydrogène, à la forme uranyle, et à nouveau transféré à une phase organique par un second procédé d'échange d'ions, cette phase organique étant ensuite lavée et débarrassee de l'uranium en utilisant une solution de carbonate de métal alcalin qui est ensuite acidifiée pour précipiter les impuretés. Application avantageuse à des sous-produits de l'industrie des engrais.
