Abstract

Abstract:

In recent years, as the development of nuclear power, the aerospace and the electric car industry, the global lithium demand increases every year. The lithium resources from brine account for about 65% of global lithium resources and 58% of global lithium products are obtained from brine. Hence, more and more researchers focus on the materials, technique and devices of lithium recovery from brine for more than a decade. The key technique of lithium recovery from brine, including precipitation, membrane, extraction and adsorption, is analyzed according to the characteristic of lithium resources around the world, particularly in China. Besides, the feasibility and future research interests of each technique are reviewed.

Key words: lithium recovery from brine, precipitation, adsorption, membranes, extraction
