Abstract Scope |
Critical minerals are essential for the green energy transition, yet their production is geographically concentrated due to limited geological availability and extraction technologies. Traditional hydrometallurgical methods are struggling to process low-grade ores and secondary sources (e.g. mining waste and e-waste) due to high contaminant levels and low concentrations of valuable metals. (Electro)Hydrometallurgy offers a promising aqueous processing approach by integrating electrochemical leaching and separation techniques, enabling higher recovery rates with reduced environmental impact. In Li brine processing, membrane separation using commercial materials has shown success, while novel polymeric membranes tailored for Li represent a significant advancement in electrodialysis. Additionally, supported liquid membranes combine the benefits of membrane and solvent extraction techniques, offering a pathway for the selective recovery of critical minerals such as Li, Ni, and Co, as well as rare earth elements as La, Nd, and Y. These innovations can enhance sustainable mineral recovery and supply chain resilience. |
