磷石膏综合利用技术进展

Technical progress on comprehensive utilization of phosphogypsum

本文介绍了在磷矿石生产磷酸时副产磷石膏的综合利用途径:提取镧系元素、作建筑材料以及制取硫酸联产水泥。建议我国制订磷石膏综合利用规划,开发综合利用新技术。

Theopaper describes the comprehensive utilization of phosphogypsurn——a byproduct from the production of phosphoric acid using phosphorus ore as raw material. The uses include the extraction of lanthanides, making construction materials and the co-production of cement with preparation of sulfuric acid.
