摘要
作为全国四大磷矿基地之一,德阳、绵竹、什邡堆积大量磷石膏,利用效率低,处理难度大。本文综述了目前磷石膏作为水泥缓凝剂、建材类制品、磷石膏基胶凝材料和矿山开采充填材料等资源化方案,但产业化程度低,阻碍技术落地推广,政府积极出台各项政策扶持科研院校和企业创新,进一步提高资源化利用率,力求全面解决磷石膏污染问题。
As one of China s four phosphate mining, phosphogypsum are stacked up yard in Mianzhu and Shifang, Deyang, which are difficult to handle.In this paper, utilization of phosphogypsum in building materials is summarized.There are four main approaches including retarder with cement, gypsum product of building materials, gypsum cementing materials and cemented filling materials.However, the basic reason is lack of practicable industrialization technologies, so that technical inefficiency of utilization and low value-added products are emerged.The government is actively introducing various policies to improve resource utilization for scientific research institutions and enterprises, striving to fully solve the problem of pollution of phosphogypsum.
