  • Rare earth elements in Australian uranium deposits

     · Rare earth elements (REE: La to Lu) are critical for high-technology applications. In Australia, undeveloped REE resources are associated with several deposit types including uranium ores. These include the Olympic Dam Cu–U–Au–Ag deposit and uranium mineralisations in the Yilgarn, Mount Painter, Olary and Mount Isa regions.
