摘　　要：采用低品级菱镁矿粉矿进行碳化浸出工艺试验,对菱镁矿的矿石性质及轻烧性能、氧化镁的消化过程和碳化浸出工艺参数进行了研究,获得wMgO大于99%的高纯氧化镁产品。The carbonization soaking of low-grade granular magnesite is studied. The mineral property and baking performance of magnesite, the digesting process of MgO as well as the technological parameters of carbonization soaking are investigated. With the carbonization soaking of magnesite, high-grade MgO has been obtained, which contains 99% of MgO.
