Evaluating Rare Earth Element Deposits
The rare earth elements are usually defined as the 14 lanthanides, from lanthanum (atomic number "Z"= 57) to lutetium with Z = 71 plus yttrium (Z= 39) as shown in Table 1. The prevailing industry practice is to exclude scandium even though it may be included in some chemistry texts. By virtue of its instability, promethium (Pm, Z=61 ...

Rare earth elements: Mendeleev's bane, modern marvels
The REs are a family of 17 metallic elements formed by the group III (Sc, Y) and the lanthanide series (La–Lu). The name "rare earth" is misleading and does not represent a geological scarcity ().The origin of this description lies in the occurrence of REs as a mixture of elements in minerals, generally at low concentration.
