Abstract

With the booming development of new energy technologies in recent years,the global demand for lithium products has increased dramatically.Due to the current situation of lithium resource endowment in China,salt lake brine has become an important source of lithium extraction.Overview of research progress on lithium extraction from salt lake brine is of great significance to the development of lithium resources in China′s salt lake brine.This work focused on membrane separation,adsorption,solvent extraction,electrochemical methods,etc.,suitable for high magnesium-to-lithium ratio brines,as well as salt gradient solar cell and precipitation methods suitable for low magnesium-to-lithium ratio brines.The advantages and disadvantages of the methods were analyzed from various aspects such as technological characteristics,performance,and extraction rate,etc.Based on the different performance of salt lake lithium extraction technologies,the adsorption coupling membrane separation method and other combined processes were discussed to have the advantages in industrialized lithium extraction from salt lake brine.Based on the existing lithium extraction technology,the ideas and directions for the development of lithium extraction from salt lake brine in China were put forward.
