青海盐湖卤水制取高纯镁砂试验技术研究

Technical research on the experiment of exacting high purity Magnesium oxide out of brine from the salt lakes of Qinghai province

通过试验发现用氨法制备高纯氧化镁是一种开发青海盐湖资源的非常有效的方法。该方法简单、产品质量稳定,氧化镁含量可达99 8%～99 95%,体积密度≥3 4g/cm3,适用于工业化生产。

High purity Magnesium oxide is prepared by Ammonia synthesis It has found in the experiment that the method is very effective in exploring salt lake resources of Qinghai province This method is simple, the quality of the product is rather steady, the content of Magnesium oxide has reached 998%～9995% and volumetric density is big or equal to 34%, it is suitable for industrial production
