Rare earth elements ("REEs") are a set of seventeen chemical include the fifteen lanthanides plus scandium and yttrium. Scandium and yttrium are rare earth elements since they are often found in the same ore deposits as the lanthanides and have similar chemical properties.. Although they are called rare, rare earth elements are not extremely rare on Earth.
The separation of pure, individual rare earths from complex ores has presented extractive chemistry with one of its greatest challenges. During the first part of the 20th century, the only technique available for separating rareearth mixtures was fractional crystallization. In one instance a rareearth researcher was said to have devoted several years of his life to carrying out 20, 000 ...
