Kinetics of leaching lightly calcined magnesia with ( NH_4)_2SO_4 (NH4)2SO4浸取轻烧氧化镁的反应动力学
The semi industrial experiments in which the tons of the dolomites was first calcined and crushed and finally ground into the magnesia cement of the caustic dolomite were carried out on the basis of the small scale experiments. 在小型试验的基础上,对用白云石为原料煅烧加工成苛性白云石镁质胶凝材料进行了半工业试验。
According to different applications magnesia can be divided into calcined magnesia, fused magnesia, heavy magnesia, industrial magnesia, activated magnesia, silicon-steel magnesia, medicinal magnesia, high purity magnesia, whiskers magnesia, nanometer magnesia and so on. 根据用途,氧化镁可分为煅烧氧化镁、电熔氧化镁、重质氧化镁、工业氧化镁、活性氧化镁、硅钢氧化镁、医药氧化镁、高纯镁砂、氧化镁晶须和纳米氧化镁等。
The dolomite is calcined to form the mixture of calcium oxide and magnesia, then the mixture is extracted by ammonium chloride solution and ammonium sulfate solution respectively. 通过对煅烧后的白云石中所含的氧化钙和氧化镁,分别采用氯化铵溶液和硫酸铵溶液进行浸提,使其中的钙、镁得到较好的分离。
