【摘要】 介绍磷石膏的主要性质及利用途径。结合目前国内磷石膏开发现状,对综合利用磷石膏存在问题进行分析,指出磷石膏利用区域发展不平衡,磷石膏品质不稳定,磷石膏制品标准体系不完善,缺乏先进的关键技术。提出新型磷酸-高品质石膏联产新技术,能够从源头上根本改变磷石膏利用困境,实现经济上可行的清洁生产工艺技术。更多还原

【Abstract】 Main properties and utilization channels of phosphogypsum are introduced. Based on the developmentstatus of phosphogypsum, the problems existing in utilization of phosphogypsum are analyzed includingimbalance of regional development, unstable phosphogypsum quality, imperfect phosphogypsum productsstandard system, lack of key advanced technology. A new technology—coproduction of new type phosphoricacid-high quality phosphogypsum is proposed, which can change the dilemma of phosphogypsum utilization in afundamental way and realize economical clean production technology.更多还原
