| Abstract: | Metallic lithium and its compounds play great role in the chemical industry, new energy and many other fields, so international market demand for lithium products to maintain sus- tained growth. The present situation of lithium resources at home and abroad was described in this paper. The production process and current situation of lithium carbonate extraction from salt lake brine were synthetically analyzed. Based on comparing with various methods of extracting lithium carbonate, the latest result of our laboratory in ion exchange and adsorption of lithium extraction was revealed. The main problems of extraction lithium from salt lake brine at present were pointed out in the end. Combined with the characteristics of salt lake brine resources in China, the developmental trend for lithium separation from brine was also pointed out. |
