  • A Critical Review On Solvent Extraction Of Rare Earths

    They are usually separated into two, three or sometimes four groups, followed by precipitation or subsequent separation of individual rare earth. Preferential separation of yttrium is desirable, and cerium and europium are often separated initially on the basis of different valance states (Ce 4+ and Eu 2+).

  • Technique For Enhanced Rare Earth Separation Science

    2000-9-29  A process is demonstrated for the efficient separation of rare earth elements, using a combination of selective reduction and vacuum distillation of halides. The large differences in the redox chemistry of the rare earth elements and in the vapor pressures of rare earth di- and trihalides are exploited for separation. Experimental proof of concept is provided for the binary systems
