西藏龙木错湖水5,℃蒸发析盐规律研究

摘要

以西藏龙木错湖水为研究对象，对其进行了5,℃低温蒸发析盐实验，研究了该湖水在蒸发过程中元素的富集行为和盐类析出规律，并依据 Na+、K+、Mg2+//Cl－、SO2－4-H2O 五元水盐体系相图进行了分析，为以后合理开发利用该盐湖提供了基础实验数据。同时，蒸发所得富锂溶液，可进行提锂工艺。%　　The aim of this research is to experimentally investigate the salting out law of the Longmucuo brine of Tibet at 5,℃. Based on the analysis of the phase diagram of Na+、K+、Mg2+//Cl-、SO2-4 -H2O,the enrichment behavior of the chemicals in the liquid phase and the salting out law of the chemicals in the brine were studied through an evaporation pro-cess at 5,℃. The maximum lithium enrichment point was found.It could be used for the extraction of lithium from this salt lake
