西台吉乃尔湖晶间卤水兑卤盐析制取硫酸锂的研究

Research on Producing Lithium Sulfate by Intercrystalline Brines from Jilaier Lake of Xitai to Salt Out

依据Li^+,Mg^(2+)//Cl-,SO_4^(2-)——H_2O四元交互体系平衡相图理论,将卤水中的锂富集到1%以上,通过兑入硫酸镁改变卤水组成及其结晶路线,析出硫酸锂。

According to the phase diagram of Li^＋,Mg^2＋∥Cl^-,SO4^2-——H2O, lithium is concentrated to more than 1% in the brine. Lithium sulfate is produced by adding magnesium sulfate into the brine,the constituents of the brine and the crystalling path can be changed.
