沉淀法分离高镁锂比盐湖卤水的研究现状

锂及其化合物因具有许多重要的特性而被广泛应用,尤其在新能源(锂电池)领域占有无法替代的地位。中国盐湖锂资源极为丰富,且多为高镁锂比的盐湖卤水,但锂资源的开发利用尚存在技术障碍。为此,结合笔者的研究成果,本文对沉淀法分离提取高镁锂比盐湖卤水的研究现状以及各方法的优缺点进行了归纳总结。

Research Situation of Separating Magnesium and Lithium from High Mg/Li Ratio Salt Lake Brine

Lithium and its compounds have many important characters,they have been extensively applied in different sectors of national economy,particularly in the field of new energy sources(lithum batteries),all because of it can not be replaced by any other compounds.However,although there are large amount of lithium resources in china,but the exploitation and utilization of numerous lithium resources are faced with the challenge of high ratio of magnesium to lithium.For this reason,combined with authors research results,the research situation and progress in separation and extraction of magnesium and lithium from high Mg/Li ratio salt lake brine by precipitation method was summarized in this article,and the advantages and disadvantages of each method were also compared.
