Specialty Nanofiltration Membranes for Lithium Extraction and Recovery from Brine

This project applies nanofiltration membrane technology to enhance lithium extraction and recovery from brine, particularly in Alberta’s lithium-rich reservoirs. The developed thin-film composite and thin-film nanocomposite membranes improve Li/Mg selectivity, lithium purity (>95%), and fouling resistance while reducing energy consumption and operational costs. By integrating these membranes into direct lithium extraction processes, this innovation supports sustainable, scalable, and cost-effective lithium production, advancing Alberta’s role in the critical minerals sector.
