Experimental results showed that an average rejection of 88 . 16 % calcium sulfate could be achieved by a two - stage flotation operation , approaching the theoretical removal ratio of 91 . 58 % from crude carnallite 实验结果表明，分级浮选法除钙率平均达88 . 16 % ，接近原矿的理论可除钙离子量91 . 58 % 。

Through the phase diagram analysis and calculation , a production method to improve the quality of carnallite by evaporating the bittern from which the sodium chloride has been eliminated by brine mixing method is presented in this paper 摘要通过相图分析及计算，介绍了一种“由盐湖卤水兑卤除氯化钠后，首先获得成矿卤水，然后对其蒸发制取质量较好光卤石矿”的生产方法。
