摘要
综述了盐湖卤水和海水锂资源提锂研究现状,尤其讨论了沉淀法、萃取法、蒸发结晶法、吸附法以及新兴的膜分离技术等盐湖卤水锂资源提锂方法,以及锂离子筛吸附剂海水提锂法,重点讨论了高镁锂比盐湖卤水的电渗析、纳滤、膜蒸馏等研究进展,提出了高镁锂比盐湖卤水开发思路。
The present situation of lithium extraction from salt lake brine and seawater were reviewed. The lithium extraction methods such as precipitation, extraction, evaporation crystallization, adsorption and the modem membrane separation technologies were especially discussed, and also the method of lithium ionic sieve adsorbent extracting lithium from seawater. In addition, the progress of electrodialysis, nanofiltration and membrane distillation for extracting lithium from salt lake brine with high magnesia lithium ratio were emphatically discussed. This paper presents the idea of the development of salt lake brine with high magnesia lithium ratio.
