Abstract

Procédé cyclique de traitement d'une liqueur uranifère contenant, outre le métal recherché, du carbonate et/ou bicarbonate de sodium et du sulfate de sodium, obtenu par l'attaque alcaline d'un minerai uranifère contenant du soufre, ledit procédé comportant la neutralisation de la liqueur uranifère puis la fixation de l'uranium et des ions SO4 - sur une résine anionique forte, leur élution par une solution de carbonate et/ou bicarbonate d'ammonium, sous la forme d'un uranyle carbonate d'ammonium ultérieurement décomposé et de sulfate d'ammonium, la précipitation et la calcination des uranates et/ou diuranates précipités avec régénération de la solution éluante de carbonate et/ou bicarbonate d'ammonium, la caustification de la liqueur débarrassée de l'uranium sortant de la résine anionique,éliminant les ions SO4 - sous la forme calcique, le recyclage d'une liqueur carbonatée et/ou bicarbonatée exempte d'ions SO4 - à l'attaque du minerai, enfin la régénération de la liqueur d'élution des ions SO4 - et de l'uranium.
