西藏鄂雅错盐湖卤水自然蒸发研究

Research of Natural Evaporation of Eyacuo Salt Lake Brine in Tibet

西藏鄂雅错盐湖湖表卤水富含K、Li及伴生有用组分B,属于硫酸盐型硫酸镁亚类盐湖。文章以西藏鄂雅错盐湖湖表卤水为研究对象,依据金作美25℃Na+、K+、Mg2+∥SO2-4、Cl--H2O五元介稳相图,研究了卤水在蒸发过程中盐类的析出规律,同时获得了卤水组成的变化规律,为盐湖下一步的开发提供了基础数据。

The surface brine of Eyacuo Salt Lake in Tibet is abundant in K,Li and accompanied useful component of B. It belongs to sulfate type and bitter salt sub-type saline. It took the surface brine of Eyacuo Salt Lake in Tibet as its research object,and investigated the precipitation regularity of salts in the evaporation progress of brine,according to the quinary metastable phase diagram of Na~＋,K~＋,Mg^（2＋）∥SO_4^（2-）,Cl^--H_2O under 25 ℃. In addition,the change regularity of brine composition was obtained,which will provide the basis for further development of saline.
