Toward Closing a Loophole : Recovering Rare Earth Elements from Uranium Metallurgical Process Tailings

Rare earth elements are increasingly required for use in modern high-tech components, and primary production is necessary to meet the demand. Reprocessing legacy metallurgical tailings is advantageous, as the material has already been mined, beneficiated, upgraded, and contained in a single accessible location. The Mary Kathleen uranium process tailings in Queensland, Australia, provides an opportunity for this. The geology and historic process methods for the Mary Kathleen uranium mine are described along with known characteristics of the tailings material. Conventional and alternative REE processing options are reviewed, including phyto-extraction and other bio-technologies. Approaches to determining the appropriate pathway forward for Mary Kathleen tailings are then discussed.
