摘要
钙镁型卤水的净化工艺和钙镁提纯利用研究,既有利节约资源,也是提高产品质量和经济效益的需要,符合国家新兴节能环保产业政策。通过改进两碱法实现钙镁分离,可以分别得到高纯度Mg(OH)2和超细CaCO3两种高价值产品。
The research of purification process of Ca-Mg type brine and the utilization of purified calcium and magnesium is not only beneficial for resources saving but also for the need of improving product quality and economic benefit and consistenting with the new national energy saving industry policy.Two high-value products——high purity Mg（OH）2 and superfine CaCO3 can be obtained by improving NaOH and Na2CO3 process to separate calcium and magnesium.
