Rare Earth Elements
Geology and Mining. 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 ...

Bayan Obo Rare Earth Mine, Inner Mongolia, China
The rare earth oxides and niobium are produced as by-products of the iron ore mining operation at Bayan Obo. The ore also contains certain radioactive elements. The ore contains a total of 15 rare earth elements with three main light rare earth elements lanthanum (La), cerium (Ce), and neodymium (Nd) found in higher percentages.
