“…Two innovative REE recovery processes from REE-enriched biomass of D. linearis have been established, and neither process requires biomass incineration. 51,52 These recovery processes are an enhanced ion-exchange leaching process and a three-step process involving extraction, oxalate precipitation, and calcination. In both methods, the critical first steps are biomass drying and grinding.…”

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.

“…One of the main workshop sites occurred in the second largest deposit of Rare-Earths in China, in a post-exploitation stage. There, the remediation initiative benefited from the humid-warm sub-tropical climate with original cultivation of Rare-Earths hyper-accumulating plants allowing Rare Earths to be extracted from polluted soils [17]. Specific efforts focused on understanding the speciation of trivalent elements in complex solution, their occurrence in contaminated soils and how to remediate them.…”

The increasing need for metals announced for the next years as part of the energy transition effort cannot be counterbalanced by the recycled metals only. Understanding the natural, anthropic and environmental life cycles of metals must become a prerequisite to further extraction-to-manufacturing development projects, as part of a global reflection and effort for developing a circular economy, increasing low carbon energy production and protecting the biosphere.The full understanding of the future evolutions of both needs and resources, and their impact on the planet and life, needs interdisciplinary research. Besides, developing an excellent analysis of environmental, social, and governance factors related to mineral resource production will help make the right decisions at all levels.

“…The contaminated biomass derived from the phytoextraction is considered as the source of NMs and REEs. The valuable metals accumulated in the plants could be recovered through extraction techniques [ [22] , [23] , [24] ]. Nonetheless, prior to the extraction process, the amount and volume of the bulky polluted biomass must be significantly decreased, then concentrations of metals are enriched into solid remains as a result.…”
