盐湖提锂工艺研究进展

Research Progress in Salt Lake Lithium Extraction Processes

随着电动汽车的快速发展,对锂资源的需求急剧增加。可开采的锂矿石资源稀缺且提取工艺复杂,而盐湖卤水中锂资源储量丰富,因此提高含锂盐湖利用率具有重要的经济意义。概述了锂资源的性质、作用、分布以及面临的挑战,论述了沉淀法、萃取法、电渗析法、电化学法以及吸附法在盐湖提锂方面的研究进展。

With the rapid development of electric vehicles,the demand for lithium resources increased dramatically.While mineable ore resources are scarce and extraction processes are complex,lithium resources are abundant in salt lake brines,making it economically important to improve the utilization of lithium-bearing salt lakes.In this paper,the nature,function,distribution and challenges of lithium resources were summarized,and the research progress of lithium extraction in salt lakes by precipitation,extraction,electrodialysis,electrochemistry and adsorption was discussed.
