摘要
系统地介绍了国内外磷尾矿资源二次利用的现状与进展,详细阐述了从磷尾矿中提取有用矿物和将磷尾矿用于制作建筑材料两种二次利用的途径。指出深入研究磷尾矿的组分特征,开发出高效的回收工艺和高附加值材料的制作工艺是磷尾矿二次利用的发展方向。
This paper systematically introduced the status and progress of secondary utilization of phosphate tailings resources at home and abroad. The extraction of useful minerals and production of building materials by using phosphate tailings were also elaborated as two approaches to secondary utilization. The studies of phosphate tailings composition characteristics and the development of efficient recovery process and production technology of high value- added materials were proposed as development directions of the secondary utilization.
