锂在国民经济中有很多重要用途,盐湖卤水中有丰富的锂资源,目前世界上从盐湖卤水中回收的锂约占总产量的40%.我国卤水提锂研究已引起有关部门的重视.“七五”期间国家“青海盐湖提钾及综合利用”重点攻关项目中,我所以溶剂萃取法提锂用青海大柴旦盐湖提硼母液为对象进行了生产50t LiCI中间试验,核工业部五所进行了树脂吸附法从察尔汗老卤提取锂盐的小试验和台架试验,我所进行了离子筛吸附法从大柴旦湖水提取锂盐的小试验.
Lithium has many important uses in the national economy, and the salt lake brine is rich in lithium resources. At present, lithium recovered from salt lake brines accounts for about 40% of the total output in China, and the research on lithium extraction from brine in our country has drawn the attention of relevant departments. During the “Seventh Five-year Plan” period, the State Key Laboratory of Extracting Potassium and Comprehensive Utilization of Qinghai Salt Lake put forward an intermediate trial of 50t LiCI for lithium extraction from the Dachaidan Salt Lake in Qinghai with solvent extraction. Five of the nuclear industry ministries carried out Resin adsorption method From Chalhan old brine extraction lithium salt small trials and bench tests, I carried out the ion sieve adsorption method from the Dachaidan lake lithium salt small trials.
