摘　　要：目前生产镁化合物的工艺存在着设备投资高、收率低和纯度低等问题，镁资源没有得到充分利用，其中钙镁分离是影响产品纯度的关键。首次采用填料塔代替传统的碳化塔，获得了白云石钙镁分离的最佳工艺条件，即碳化温度为50℃～60℃，碳化时间为15min。At present the technologies of producing magnesium compounds have many problems such as： high investment, low receiving rate and had purity etc. The resources of mgnesium have not been utilized fully. The separation of calcium and magnesium is the key in affecting produce purity. The filled tower has been used instead of traditional carbonization tower in the process firstly. The optimum conditions were given as follow： carbonization temperature 50 ℃ -60 ℃, carbonization time 15 min.
