摘要
介绍了以硫酸铵、白云石为原料制备硫酸镁、氢氧化镁、轻质氧化镁的实验条件及工艺过程。讨论了实验条件对产品质量、性能的影响。与白云石的开发利用其它工艺比较 ,该方法具有原料来源方便、生产成本较低等优点 ,无三废污染 ,废渣可加工成CaSO4 产品 。
The preparation of MgSO 4,Mg(OH) 2,MgO dolomite and ammonium sulfate by reverse extraction has been studied.The factors of influencing on the quality and performance of product are discussed.The experiment results show that this method has many advantages,such as easily obtained resource and cheap technology cost,without waste pollution and recovery of waste sludge and gas etc.
