- The effects of washing method, lime neutralization, flotation method and microwave method of different pretreatment process of Yunnan phosphorus building gypsum strength and crystal morphology. Through, a lot of experiments comparing the four kinds of pretreatment effect, the results show that: after four pretreatment of phosphogypsum are basically meet the requirements of the relevant provisions of building materials products; compared wih the other three methods, microwave method possessed the better effect of moving fluoride and organic matter in phosphorus gypsum,smaller losses of gypsum content,etc. Environmental protection, easy for factory operated, as well as high strength.
