察尔汗盐湖东、西采区原卤兑卤除钙试验研究

Experimental research on removal of calcium in raw brine by mixing brine in the east and west mining areas of Qarhan Salt Lake

对察尔汗盐湖两种不同类型原卤(氯化物型和硫酸镁亚型)混合使用时如何减少和控制CaSO4·2H2O的析出进行了定量和定性的研究。通过兑卤试验,找到了满足生产的兑卤比例和钙的最佳析出点,掌握了CaSO4的析出规律,为更好地利用东、西采区原卤提供了准确的数据。

Quantitative and qualitative researches were made on the two different types of raw brine （chloride type and magnesium sulfate type）to reduce and control precipitation of CaSO4 · 2 H2O while its mixed use. The ratio of mixing brine and the optimum calcium precipitation point to accommodate the production were found and the CaSO4 precipitation rule was obtained, providing the correct data for better utilization of the east and west mining areas.
