Europium separation from a middle rare earth concentrate has been achieved successfully by using the combined chemical reduction–precipitation technique. The separation method depends on the reduction of europium by metallic zinc to its bivalent oxidation state followed by selective precipitation of the sparingly soluble europium (II) sulphate, while leaving the other rare earth sulphates in ...
