Rare earths (“REEs”) are classified as “light” and “heavy” based on atomic number. Light REEs (“LREEs”) are comprised of lanthanum through samarium (atomic numbers 57 through 62), while heavy REEs (“HREEs”) are comprised of europium through lutetium (atomic numbers 63 through 71) and yttrium (atomic number 39), which has similar an ionic radius and chemical and physical attributes to the HREEs. HREEs tend to be less abundant and more expensive than LREEs.

Some rare earth elements have magnetic properties: Neodymium, Praseodymium, Dysprosium, and Terbium. Neodymium and praseodymium are key critical materials in the manufacturing of magnets that have the highest magnetic strength among commercially available magnets and enable high energy density and high energy efficiency in diverse uses. Dysprosium and terbium are key critical materials often added to the magnet alloys to increase the operating temperature.

In this report, rare earths are also presented in oxides according to the following grouping:
