西藏鄂雅错盐湖卤水兑卤蒸发研究

Study on Mixing Brine Evaporation of Brine From E Yacuo Salt Lake in Tibet

用鄂雅错盐湖卤水进行兑卤,通过改变卤水的镁钾比,使其在蒸发过程中不会析出钾石盐,直接析出含钾品位较高的光卤石。实验结果表明:兑卤蒸发的析盐顺序为氯化钠、硫酸镁—氯化钠、光卤石,蒸发过程中钾收率达79.26%。

The mixing brine of the brine from E yacuo salt lake was carried out to change Mg/K ratio in the brine, which could make the evaporation process precipitate carnallite with higher grade potassium instead of sylvite. The experimental results show that：the crystallization order of evaporation is sodium chloride, magnesium sulfate-sodium chloride, carnallite. Potassium yield is 79.26%.
