    • 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 ...

    • 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.
