Rare-earth element - Wikipedia

The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...

Recycling of rare earths: a critical review - ScienceDirect

15/07/2013  The rare earths or rare-earth elements (REEs) are a group of 17 chemically similar metallic elements (15 lanthanides, plus scandium and yttrium). They are becoming increasingly important in the transition to a green, low-carbon economy. This is due to their essential role in permanent magnets, lamp phosphors, rechargeable NiMH batteries, catalysts and other applications (Tables 1 and 2).
