Research Progress of Lithium Extraction from Raw Brine in Salt Lake
In recent years,with the rapid development of new energy vehicles and energy storage batteries,the consumption of lithium products is increasing,the development and utilization of lithium resources has received a high degree of attention.The currently industrialized lithium extraction method has a long production cycle,low lithium recovery rate,and a slow growth in lithium production,which is difficult to meet the needs of China's new energy industry development.Direct extraction of lithium from low-lithium brine can realize the efficient utilization of low-grade lithium resources,which is of great significance for improving the supply of strategic lithium resources in China.Based on the characteristics of brine resources,this paper summarizes the adsorption,membrane separation,solvent extraction and others methods,which applicable to the extraction of lithium from low lithium concentration and high magnesium lithium ratio of raw brine.The characteristics and effects of various lithium extraction methods were analyzed.The development trend of extracting lithium from brine with low lithium concentration and high magnesium lithium ratio is expected.
