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. The concentration of cerium, the most abundant rare ...
