PREPARATION OF URANIUM-BEARING STOCK FOR EXTRACTION Russian patent published in 2014 - IPC C22B60/02 C22B3/06 C22B3/38

Abstract RU 2514557 C1

FIELD: metallurgy.

SUBSTANCE: proposed process comprises leaching of uranium by nitric acid and separation of water phase from undissolved precipitate. Then, undissolved precipitate is mixed with fluorine-bearing agent, dissolution of produced charge and/or charge as a suspension in nitric acid solution. Produced solution is returned to production process for extraction of uranium. Nitric acid concentration in solution makes at least 2 mol/l. Dilution is carried out at fluorine-ion concentration at, at least, 15 g/l. Dilution is performed at 60-100°C.

EFFECT: decreased losses of uranium, minimised wastes.
