Mixed nitrates of thorium and rare earths may be enriched to more than 80% in thorium nitrate by leaching with any of several alcohols or ketones. The type of leaching considered consists in agitating the solid mixed nitrates with an appropriate amount of any of the higher alcohols or ketones. A batch of saturated solution is withdrawn and agitated with an equal volume of water until practically all the extracted nitrates enter the aqueous phase. The product is crystallized from the aqueous phase by evaporation and the washed organic solvent saved for re-use. The attainable thorium enrichment increases within a homologous series of alcohols or ketones with increasing molecular weight.
