Yttrium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium are the "heavy rare earths." Although yttrium is lighter than the light rare earth elements, it is included in the heavy rare earth group because of its chemical and physical associations with heavy rare earths in natural deposits.

The rare earth elements (REE) or rare earth metals (REM), of which there are 15 in number, occur together in nature with two nonlanthanide elements, scandium and yttrium. All 17 elements behave similarly chemically.
There are currently more than 400 projects related to rare earth exploration outside of China ("Rare Earths"). Interest in REE mining has likewise increased: feasibility studies are ongoing at 40+ new sites being evaluated in the US, Canada, Australia, India, Malawi and South Africa (Schuler 2011, Werdon).
