The estimated average concentration of the rare earth elements in the Earth''s crust, which ranges from around 150 to 220 parts per million (table 1), exceeds that of many other metals that are mined on an industrial scale, such as copper (55 parts per million) and zinc (70 parts per million).
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.
Eriez Rare Earth (RE) Roll Magnetic Separators are used extensively in the mineral sands industry for the magnetic concentration of weakly magnetic minerals, such as garnet, ilmenite, musovite, mica, etc.
