摘要
针对我国铁尾矿年产量超6亿t、堆存风险突出与资源浪费问题,系统研究了其规模化管控与高值化利用路径,以破解环境风险与资源循环协同治理难题,构建了“源头减量—过程控制—末端利用”全链条技术体系,指出大宗利用存在充填受限于露天矿山场景缺失与细粒化问题,建材化推广受运输成本及标准缺失制约,但高值化利用前景广阔。最后得出铁尾矿综合利用依赖技术-政策协同创新,细粒尾矿活化改性、多组分梯级回收技术的突破,跨领域标准体系的建立,规模化消纳的核心方向是生态化利用,未来需聚焦铁尾矿全量化目标与智能化管控。
In response to the annual production of over 600 million tons of iron tailings in China,the prominent risks of stockpiling and the waste of resources,a systematic study was conducted on the large-scale management and high-value utiliza-tion of iron tailings to address the challenge of coordinated governance of environmental risks and resource recycling.A full-chain technical system of"source reduction,process control,end utilization"was established.It was pointed out that the large-scale utilization is restricted by the lack of open-pit mining scenarios and the fine-grained problem for backfilling,and the pro-motion of building materials is constrained by transportation costs and the absence of standards.However,the prospects for high-value utilization are broad.Finally,it was concluded that the comprehensive utilization of iron tailings relies on the collab-orative innovation of technology and policy,the breakthrough of fine-grained tailings activation and modification,and multi-com-ponent stepwise recovery technologies,the establishment of cross-domain standard systems,and the core direction of large-scale absorption is ecological utilization.In the future,the goal of full quantification and intelligent management of iron tailings should be focused on.
