The phosphogypsum calcining technology for building gypsum production and the problems should be paid attention to

介绍了国内外利用磷石膏制取半水石膏的的最新进展,重点分析了"一步法"和"两步法"制备建筑石膏的工艺特点,并对其中应注意的相关问题提出了一些建议,以期为磷石膏煅烧建筑石膏的产业化生产提供参考。

This paper introduced the latest development progress of making semi-hydrated gypsum from phesphogypsum at home and abroad,and emphatically analyzed the technological characteristics of building gypsum produced by ＂one-step method＂ and ＂two-step method＂. This paper also put forward some suggestions on the relevant issues that should be paid attention to, in order to provide reference for the industrialized production of phosphogypsum calcined building gypsum.
