Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] throug
Rare Earth Metal Mining You must successfully locate REMs in order to determine its viability as a source worth mining. Unlike other metals often found in ore deposits and veins that can be economically mined, earth elements are typically found in alkaline and igneous rocks and are not detected...
The rare earth elements are the group of 15 chemically similar elements with atomic numbers between 57 and 71 inclusive: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium (together making up the light' or 'cerium' subgroup), gadolinium, terbium, dysprosium, holmium, erbium...

The rare earth elements are all metals, and the group is often referred to as the "rare earth metals." These metals have many similar properties, and that often causes them to be found together in geologic deposits. They are also referred to as "rare earth oxides" because many of them ...
