Magnesite is the key raw material for the preparation of magnesium flame retardant materials,and its chemical properties can be greatly enhanced by using acidification and carbonisation modification processes.Carbonation method has only react with magnesium in magnesite and carbonation pyrolysis product magnesium alkali hydrochloride morphology is easy to control,can be prepared with different morphology of high purity magnesium oxide calcined precursor magnesium alkali carbonate,to get high purity,high activity,good morphology magnesium oxide,to achieve the high value-added use of China's magnesite resources.The research progress of magnesite decontamination application technology in recent years is summarised,and the advantages and characteristics of each method are described.
