Abstract

A crude solution containing thorium, such as that obtained by digesting monazite sand with sulphuric acid and leaching the residue, is, preferably in a slightly acid condition, treated with a soluble fluoride or hydrofluoric acid in quantity sufficient only to precipitate the thorium. Preferably the precipitant is first added in quantity only sufficient to precipitate a portion of the thorium, and then the solution is further diluted and the rest of the precipitant is added to precipitate the remainder. If a fluoride is used as precipitant, a double fluoride such as thorium-potassium fluoride is produced. If desired, the fluoride may be purified further by converting into hydrate as described in Specification 127,555, dissolving in sulphuric acid, and again precipitating as above described. Reference has been directed by the Comptroller to Specification 127,555.
