摘要
将磷石膏采用不同温度煅烧和蒸养的方式进行预处理,通过测定各种不同预处理磷石膏中可溶磷、可溶氟的含量,对比研究不同预处理方式对磷石膏水溶性杂质的去除效果;并通过XRD、SEM分析不同预处理磷石膏的矿物组成及微观结构。
Phosphogypsum（PG） was pretreated by different temperatures of calcining and autoclaving. The water soluble impurity contents of original PG, calcined PG and autoclaved PG samples were quantitatively determined. The calcined and autoclaved pretreatments on the water soluble impurities removal of phosphogypsum were studied comparativly. The comparison of crystalline phase and morphology between original and pretreated PG were also studied.
