Australia hosts some of the most critical rare earth mining and processing enterprises operating outside of China. The major industry leaders include Lynas Rare Earths (the dominant global producer of separated rare earth oxides from its Mt Weld deposit), Iluka Resources (constructing the Eneabba rare earths refinery), Arafura Rare Earths (developer of the Nolans Bore project), Hastings Technology Metals, and Australian Strategic Materials. These companies supply vital materials necessary for permanent magnets, electric vehicles, and defense electronics.
