The processes used in Sweden for the production of uranium oxide and metal from uranous phosphate concontrate are presented. The refining process involves digestion of the uranous phosphate with caustic soda, conversion of the uranous hydroxide to ammonium uranyl carbonate, dissolution in nitric acid, and purification by solvent extraction using hexone. Ammonium uranatc is recovered from the pure uranyl nitrate solution by homogenous precipitation with urea. After calcination the UO/sub 3/ product is reduced to UO/sub 2/, converted to UF/ sub 4/ dryway'' hydrofluorination process, and reduced by calcium to U metal, which subsequently is remelted under vacuum.
