| 中文摘要: |
| 铅锌尾矿是浮选铅锌矿石过程中产生的主要固体废弃物，其成分复杂，除残留有价金属外，还伴生多种可回收的非金属矿物，资源化利用潜力较大。 为推动铅锌尾矿的高效资源化、规模减量化及安全无害化工作，本文系统梳理了铅锌尾矿资源化利用的研究现状、发展趋势及综合利用方法，选取甘肃省某个典型铅锌尾矿库为研究对象，开展了铅锌尾矿调查与综合利用研究。 根据尾矿岩芯样品的物理性质、化学性质，提出了铅锌尾矿有价组分再回收、制备凝胶材料充填采空区、制备高附加值产品及土地复垦、生态修复等综合利用建议，以期为我省尾矿资源化综合利用提供参考。 |
| 英文摘要: |
| Lead-zinc tailings are the primary solid waste generated during the flotation process of lead-zinc ores, typically categorized into silicate -type and carbonate -type tailings. They are complex in compositio n ,containing not only residual valuable metals but also various recoverable non -metallic minerals, indicating significant potential for resource utilization. To promote the high -efficiency resource utilization, large -scale reduction, and safe, non -hazardous treatment of lead -zinc tailings in our province, this paper systematically reviews the current research status, development trends, and comprehensive utilization methods for the resource recovery of lead -zinc tailings. A typical lead -zinc tailings pond in our province was selected as the study subject, and an investigation along with comprehensive utilization research on the tailings was conducted. Based on the physical and chemical properties of tailings core samples, this study proposes comprehensive utilization strategies, including the re -recovery of valuable components from lead -zinc tailings, the preparation of gel materials for backfilling mined -out areas, the production of high -value -added products, as well as land reclamation and ecological restoration. These recommendations aim to provide a reference for the comprehensive resource utilization of tailings in the province, thereby effectively supporting natural resource management, ecological civilization construction, and socio-economic development。 |
