磷石膏中钙源的回收与利用研究现状

Research Status for Recovery and Utilization of Calcium in Phosphogypsum

磷石膏是磷复肥生产过程中的副产物,随着中国磷复肥工业的快速发展,磷石膏处理已成为当前急需解决的环保和安全问题。目前国内外对磷石膏综合利用的报道较多,但针对磷石膏中钙资源的回收与利用的综合报道鲜有。根据磷石膏综合利用的现有报道,综述了磷石膏中钙资源的回收与利用研究现状。

Phosphogypsum is a by-product in the production process of phosphatic compound fertilizer. With the rapid development of phosphatic compound fertilizer industry in China, phosphogypsum processing has become the issue of environmental protection and security which badly needs to be solved. There are lots of reports about the comprehensive utilization of phosphogypsum both at home and abroad, but few re ports are about the comprehensive recovery and utilization of calcium in phosphogypsum. Based on the reports of comprehensive utilization of phosphogypsum, research status of recovery and utilization of calcium in phosphogypsum are introduced in this paper.
