察尔汗盐湖低品位卤水自然蒸发试验研究

Study on the Natural Evaporation of Low Grade Brines from Chaerhan Salt Lake

察尔汗盐湖是一个以卤水钾镁盐矿为主的大型综合性盐类矿床,盐湖东部潜卤水水化学类型为氯化物型,从KCl等组份含量来看,属低钾高钠低镁的卤水。对该类型卤水进行自然蒸发试验,确定盐类结晶析出顺序和光卤石矿物的最佳分离点,取得光卤石矿的产率和光卤石中KCl含量等基础数据,以对该卤水工业利用性能作出评价。

Chaerhan Salt Lake is a large composite salt deposit with the primary composition of potassium and magnesium brines. The brines feature high sodium contents, but low potassium and magnesium contents. The present work involved the natural evaporation of the brines, for the determination of the crystallization sequences of different minerals and the optimal separation points of eamallite. Fundamental data of the yields of camallite and its KCl contents were obtained for the evaluation of the feasibility of utilizing the brines.
