利用盐湖高钙含钾卤水制取氯化钾工艺试验研究

Study and Test of Process of Production of Potassium Chloride from High Calcium Potassium Bearing Brine in Salt Lake

青海盐湖部分氯化物型卤水中,由于钙的循环积累,其浓度不断增高,这可能对从卤水中提取氯化钾带来一定影响。实验研究了该类型高钙含钾卤水对4#工艺制取氯化钾的影响,研究结果表明卤水中钙含量对4#工艺制取氯化钾影响较小。

In some of chloride-type brine in Salt Lake of Qinghai.the cycling accumulation of calcium results in increasing growth of its concetration,which probably will make some effect on the production of potassium chloride from brine.This paper makes research on impact this type of high calcium potassium bearing brine has on production of potassium chloride by 4# Process.The research results show that calcium content in brine would have less impact on production of potassium chloride by 4# Process.
