The radioactive minerals from Venta de Cardena (Cordoba), with an average U/sub 3/O/sub 8/ content of 0.4% in the form of metaautunite I and torbernite can be beneficiated with almost quantitative yield by heat treatment (80 to 90 deg C) for three hours with 3% solution with sodium carbonate. From the uranyl carbonate complex high purity uranium peroxide can be precipitated quantitatively by acidification with nitric acid to pH 2, after addition of hydrogen peroxide and heating to 60 deg C. At room temperature with pH 5, it is possible to precipitate high purity aranyl phosphate from the leach solution with a yield of 98%. (tr-auth)
