The
thirty rare earth elements(or rare earth metals) are composed of the lanthanide
and actinide series. One element of the lanthanide series and most of the elements
in the actinide series are called trans-uranium, which means synthetic or man-made.
All of the rare earth metals are found in group 3 of the periodic table, and the
6th and 7th periods.

The
rare-earth elements are the 15 lanthanide-series elements are generally
included with the REEs, as they often occur with the lanthanides and have
similar chemical properties.
Ion exchange columns and solvent extraction
processes are used to quickly separate and purify rare earths and then quantified
using ICP-AES analysis.
