recury of uranium from uranium ores

    • RECOVERY OF URANIUM FROM ORES (Journal Article)

    Abstract. Uranium is recovered from an ore by forming, from the ore, a clear solution of a hexavalent uranyl-alkali metal or -ammonium carbonate solution, precipitating hydrated UO/sub 2/ from the solution by forming nascent hydrogen therein and separating this oxide.

    • RECOVERY OF URANIUM FROM ORES THEREOF

    RECOVERY OF URANIUM FROM ORES THEREOF. Full Record; Other Related Research; Abstract. A resin-in-pulp process for U recovery from ores is described. The ore is ground, leached with H/sub 2/SO/sub 4/, and the leach pulp plus pregnant liquor are exposed to pieces of anion exchange resin which can later be screened out. (T.R.H.)

    • RECOVERY OF URANIUM FROM LOW GRADE

    2021-5-18  A method is given for recovering uranium from lowgrade geologic deposits. The method consists in chlorinating the inorganic portions of the ore at a temperature sufficient to form a volatile chloride stream containing the desired uranium. The volatilized chloride stream is then contacted with a ...

    • RECOVERY OF URANIUM FROM PHOSPHATE ORES

    2021-6-3  Uranium ore from Radium Hill, South Australia was leached with hot sulfuric acid solutions and the uranium recovered from solution by uranous phosphate precipitation or by use of anion exchange resins. 94 to 98% of the uranium was recovered at a grade of 52 to 65% U3O6 by uranous phosphate precipitation.

    • Flotation of uranium from uranium ores in canada:

    The best results were obtained with cupferron, where 93‐95% of the uranium was recovered in 25‐30% of the mass of original ore. Radium in the tails varied between 15 and 30 pCi/g depending on the mass of uranium floated. Radium was recovered in proportion to uranium in the tests done at neutral pH.

    • Ferric nitrate leaching of uranium and radium from

    1985-10-1  Treatments of uranium ores with nitric acid [3], hydrochloric acid [4], chlorination [5], and ferric chloride [6, 7] have been suggested for this coextraction, and the literature is reviewed by Nir- dosh et al. [7]. Ferric nitrate is considered in this work as a possible leaching agent for uranium and radium from the ores.
