Current Status and Research Progress of Lithium Extraction Technology for Lithium-bearing Resources
Lithium resources are abundant but highly concentrated,with obvious regional supply and demand mismatches and limited development and utilization technologies,on a basis of which the paper analyzes the classification of lithium-bearing resources and its main characteristics,focusing on the traditional lithium extraction technology from salt lake brine such as precipitation process,extraction process and adsorption process,as well as lithium extraction from ores such as sulphuric acid process,lime sintering process and sulphate process,analyzing the advantages and disadvantages of these traditional processes.Furthermore,the paper introduces and looks forward to the development direction of the new lithium extraction technologies such as lithium extraction by nano-filtering membrane,lithium extraction by biological method and lithium extraction from electrochemical ions.
