Thulium Production


During processing of rare earth elements thulium concentrates with heaviest elements - ytterbium and lutetium. Thulium is separated from natural rare earth elements mixture by extraction method and ion exchange chromatography using chelates (complexions).

Thulium metal as Holmium is reduced from TmF3 by calcium or from Tm2O3 by lanthanum.
