摘　　要：碳化法从硼泥中制取轻质碳酸镁是在催化剂作用下,利用石灰Ca(OH)2和硼泥中的MgCO3经转化反应生成易于碳化的Mg(OH)2,后经碳化、热解等操作制取轻质碳酸镁的一种经济、有效、工艺简单的提镁方法。其中转化反应是影响镁提取率高低的主要因素,文章通过实验讨论了影响转化反应的几个重要因素,确定了最佳转化反应条件。实验表明,镁制取率高,轻质碳酸镁质量符合HG/T2959—1988(1997)的标准要求。It is an economic, effective and easy method to recovery the lightened magnesium carbonate from boronic mud with carboni- zing method, which produces the easily carbonized Mg（OH） 2 used the transformative reaction from Ca（ OH ）2 and MgCO3 in the boron- ic mud. In the process,the,transformative reaction is the decisive factor affecting the recovery of magnesium. By experiment, the paper discusses some important factors which affect the transformative reaction and gets the optimal condition. As a result, it has high recov- ery, the lightened magnesium carbonate satisfy the standard HG/T2959-1988（1997）.
