Supercritical Fluid Extraction of Rare-Earth Elements from a Canadian Oreo chelating agent ratio, residence time, and agitation rate on the extraction efficiency. The results of this work demonstrate the viability of utilizing SCFE as a cleaner and more sustainable option to extract REEs from primary resources.

Optimizing Zr and REE Recovery from Zircon Through a Better Understanding of the Mechanisms Governin. Considering that annealing kinetics is faster than the decomposition rate, we demonstrate that, for certain REE-rich zircons, a process can be designed where >95% Zr and REE recovery is achieved below 200 °C, while treatment at higher temperatures is detrimental, rendering the crystals less reactive.

An Innovative Process for Extracting Scandium from Nickeliferous Laterite Orezed to investigate the effect of various operating parameters during the smelting and the leaching processes and to optimize the processes. After optimization, 88% of scandium was recovered during the NaOH cracking process.

POINT

Recovery of Strategic Materials from Canadian Bauxite Residue by Smelting Followed by Acid Baking–Wacterizations were used to gain an understanding of the underlying physicochemical mechanisms. This waste valorization process is intended to be integrated into a larger near-zero-waste process to sustainably recover the valuable components of bauxite residue to help build the circular economy.

Selective Lithium Recovery from Brines Using Hydrothermally Treated Titania Slag. In this work, we have synthesized LTO from waste titania slag and immobilized on a diatomaceous earth (DE) support. Titania slag was hydrothermally treated in alkaline solution to remove slag impurities. Acidic leaching followed by hydrolysis was performed to dissolve impurities and immobilize TiO
