中文摘要:

      利用资源丰富的青海察尔汗盐湖卤水，通过蒸发结晶、净化脱硫、兑卤、分段析盐和洗涤等加工处理，提取优质光卤石，使之满足炼镁指标要求，以替代人造光卤石电解制取金属镁．此外，亦可用于冷结晶法生产氯化钾．

英文摘要:

      The high quality carnallite is obtained from the brine of Qarhan salt lake with rich salt resources, by evaporation, deaulfization, mixing two different kinds of brine, crystallizing and washing respectively. It is satisfied with the requirement of electrolyzing the metal of Magnesium, and can take the place of the carnallite recovered from the crude carnallite for preparation of Magnesium. In addition, it can be used as raw material in the production of Potassium Chloride by the method of cool-crystallizing.
