ABSTRACT:
Rare earth, uranium and thorium values are separated and recovered from aqueous solutions of the chlorides thereof, said aqueous solutions having an acidity of less than 2 N and a concentration in such values, expressed as the oxides thereof, of at least 50 g/l, by liquid-liquid extracting said aqueous solutions with an organic extractant comprising at least one neutral organophosphorus compound.
