Research on Cooling Crystallization Process in Preparation of Mirabilite and Epsomite from Astrakanite
XIE Chao,ZHENG Xian-fu,TANG Jian-liang,SUN Cheng-gao (Changsha Design and Research Institute,Ministry of Chemical Industry,Changsha 410116,China)
Abstract:A process of extracting mirabilite and epsomite from astrakanite was investigated,which overcomes the deficits of the traditional process by cutting off the process of separation of astrakanite. The results showed that the process was of lower energy consumption,lower cost,but easy to operate with higher economic benefits. In addition,resources of sodium sulfate and magnesium sulfate can be fully utilized therein.
Key words:astrakanite;mirabilite;epsomite
