Abstract

As the extraction process of lithium resources from Salt Lake brine is simpler than lithium extraction from ore, lower cost, less environmental pollution and can meet the current demand of lithium products market, countries around the world have turned to the development of lithium extraction from Salt Lake brine as a major direction. At present, the main membrane related technologies for lithium extraction from Salt Lake brine are: nanofiltration membrane filtration, electrodialysis, ion exchange adsorption and covalent organic skeleton membrane separation. We will review the research progress of membrane technology for lithium extraction from Salt Lake starting from the above membrane related technologies.
