Abstract

Rare earth values are separated from uranium values in an aqueous solution by contacting the solution with an inorganic water-insoluble fluoride; the rare earths are adsorbed by the fluoride and the uranium remains in solution. Suitable fluorides are calcium fluoride, e.g. fluorite, rare earth, e.g. lanthanum, fluorides, and thorium fluoride. The aqueous solution may be at a temperature of 25 DEG to 300 DEG C. and may be acidified before contact with the fluoride. The process is especially suitable for treating a solution of uranyl sulphate in deuterium oxide which has been used in a nuclear reactor, but may also be applied to uranium solutions obtained from ore processing. In examples, rare earths including cerium and yttrium are separated from uranyl sulphite solutions containing sulphuric acid.
