摘要
磷石膏是湿法工艺制取磷酸过程中产生的工业副产品,作为全国磷矿主产区之一的贵州,率先提出了“以渣定产”政策,以促进磷石膏的综合利用。以磷石膏新型建材应用为重点方向,对磷石膏资源的综合利用进行了介绍。
Phosphogypsum is a by-product of the production process in wet-process phosphoric acid.Guizhou,as one of the main phosphate rock production areas in China,took the lead in putting forward the policy of "production by slag" to promote the comprehensive utilization of phosphogypsum.Focuses on the application of phosphogypsum in new building materials,and the comprehensive utilization of phosphogypsum resources is introduced in this paper.
