Direct lithium extraction from extreme environments
As the demand for lithium continues to grow, supply is expected to fall short of demand as early as next year, with up to 75% of the world’s lithium-rich saltwater sources remaining untappable using current methods. Monash University engineers have developed world-first technology, EDTA-aided loose nanofiltration (EALNF), enabling direct lithium extraction from difficult-to-process sources. The technology extracts both lithium and magnesium simultaneously, unlike traditional methods that treat magnesium salts as waste, making it smarter, faster and more sustainable. The work, co-led by Dr Zhikao Li, from the Monash Suzhou Research Institute and the Department of Chemical and Biological Engineering, and Professor Xiwang Zhang from the University of Queensland, paves the way for more sustainable and efficient extraction practices.
