The development of the global lithium resources is reviewed, and the lithium resources situation in China is introduced. Main processes of lithium extraction, including extraction from brine, ore and sea water, are elaborated separately. Comparison and analysis on the advantages and disadvantages of the three processes are also provided. Based on the analysis on the price changes of lithium in recent decades, an inference of the significance of lithium carbonate on the electric vehicle industry in the future is proposed. It would be a relevant evidence for exhaustive study on the industrial structure, the utilization rate, and the extraction technology of lithium extraction from salt lake.%综述了全球锂资源的发展状况,简述了我国锂资源状况.分别阐述了卤水提锂、矿石提锂、海水提锂3种工艺,对比分析了3种工艺的优缺点.重点分析了近几十年来锂的价格变化,推论了碳酸锂对未来电动汽车产业的重要性.为深度研究盐湖提锂产业结构,提高盐湖提锂的利用率,改善其分离技术提供了相关佐证.
