Rare earth elements occur in many minerals but typically in concentrations too low to be refined in an economical manner; the concentration of REEs in the Earth's crust is estimated to be between 150 to 220 parts per million, which is higher than the concentration of other metals mined for industrial use, such as Cu or Zn.

Rare-earth element - Abundance, Occurrence, Reserves: As noted above, the rare earths are fairly abundant, but their availability is somewhat limited, primarily because their concentration levels in many ores are quite low (less than 5 percent by weight). An economically viable source should contain more than 5 percent rare earths, unless they …

Yes, quite. In 2018, the cost for an oxide of neodymium, atomic number 60, is US$107,000 per metric ton. The price is expected to climb to $150,000 by 2025. Europium is even more costly – about ...

Found in the Earth's crust, rare earths are critical elements used in cars, consumer electronics, computers, communications, clean energy and defense systems. There are 17 elements that are considered to be rare earth elements (REE). Fifteen of those elements are in the lanthanide series and two additional elements share similar …

The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's crust at 60 parts per million, to thulium and lutetium, the least abundant rare-earth elements at about 0. ...

The Journal of Rare Earths reports studies on the 17 rare earth elements.

Rare-earth element - Minerals, Ores, Uses: The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as "light" or "heavy"; in the former group most of the elements present are the light-atomic-weight elements (i.e., lanthanum, cerium, …

The rare earths are 17 metallic elements, located in the middle of the periodic table (atomic numbers 21, 39, and 57–71). These metals have unusual fluorescent, conductive, and magnetic properties—which make them very useful when alloyed, or mixed, in small quantities with more common metals such as iron. Geologically speaking, the rare ...
