Separation of Rare Earth Elements - American Chemical

In a laboratory in Conant Hall, James devised novel fractional crystallization techniques for separating rare earth elements, which were widely adopted by other chemists. James used his method to separate large amounts of ytterbium, previously considered to be a single element, into two elements now known as ytterbium and lutetium.

Rare Earth Extraction - an overview ScienceDirect Topics

When a rare-earth extraction-separation process with constant mixed extraction ratio is started, the concentration of each component in each stage gradually changes with the more extractable component moving into the scrub section as organic phase moves, and the less extractable component moving into the extraction section as aqueous phase moves.
