RECOVERY OF URANIUM VALUES FROM URANIUM-BEARING RAW MATERIALS
An inmproved acid leaching process for extracting small amounts of uranium from raw materials (ores and concentrates) is described in which the iron salts in the leach solution are replaced with manganese dioxide for economy and for more effective oxidation of uranium to the hexavalent state. It is desirable, however, to have a small amount of soluble iron present to catalyze the oxidation rraction and thus speed up its rste; and in the case of ores having a high phosphate content, it is necessary to add more ferric ions to complex the phosphate in order to prevent it from precipitating with the uranium when base is added. Three examples and a flowsheet of the process are presented. (D.L.C.)
