我国磷矿资源节约与综合利用关键技术

Key Technology of Saving and Comprehensive Utilization of Phosphate Rock Resources in China

为落实节约优先战略,推进磷矿资源节约与综合利用建设,对我国磷矿资源及资源节约与综合利用现状进行了调查总结,通过分析磷矿资源开发利用链,指出我国磷矿资源节约与综合利用急需解决的9项关键技术:磷矿石工业品位指标体系研究;磷矿资源节约与综合利用评价体系研究;磷矿勘探、生产数字化设计与管控技术;倾斜缓倾斜、薄至中厚磷矿层高效、低耗采矿技术及装备;中低品位胶磷矿高效、低耗浮选技术及装备;共、伴生资源综合回收利用技术;以净化湿法磷酸为原料的精细磷化工技术;磷石膏综合利用与无害处理技术;磷资源回收利用技术。

In order to implement the strategy of saving preferential, promote the saving and compre- hensive utilization of phosphate rock resources, phosphate rock resources and resources conservation and current situation of comprehensive utilization in China are investigated. Through analysis of development and utilization chain of phosphate rock resources, 9 key technologies which need to be solved urgently on conservation and comprehensive utilization of phosphate rock resources in China are pointed out, research of index system for phosphorus ore industrial grade; research of evaluation system for conservation and comprehensive utilization of phosphate rock resources; phosphorus ore exploration, digital production de- sign and management-control technology; mining technology and equipment with high efficiency and low consumption for the inclined, gently inclined and thin to medium thickness phosphorus deposits; high ef- ficiency and low consumption flotation technology and equipment for mid-low grade collophanite; compre- hensive recovery utilization technology for intergrowth and associated resources; fine phosphorous chemi- cal technology using purified wet-process phosphoric acid as raw material; phosphogypsum comprehensive utilization and harmless treatment technology; phosphorus resource recovery and utilization technoln~,v
