摘　　要：有色金属矿山尾矿产生量大、成分复杂、重金属含量高、利用率低,堆存不仅占用大量土地,而且对周边环境也存在一定的污染隐患。以尾矿经过土壤化改良后形成的“人造土”为基质进行生态修复是一种新型的绿色、高效和可持续化的尾矿综合利用方式。阐述了有色金属矿山典型尾矿土壤化技术,分析了铅锌尾矿、铜尾矿、黄金尾矿、稀土尾矿土壤化技术现状,探讨了有色金属尾矿土壤化面临的挑战,并进行了展望,以期为有色金属矿山大宗尾矿资源的绿色综合利用提供参考依据。Non-ferrous metal mine tailings are characterized by large quantities,complex compositions,high heavy metal content,and low utilization rates.The stockpiling of these tailings not only occupies vast tracts of land but also poses potential environmental pollution risks.Using"artificial soil"formed by tailings soilification as a substrate for ecological restoration represents a novel,green,efficient,and sustainable approach to comprehensive tailings utilization.This paper elaborates on the typical soilification technologies for non-ferrous metal mine tailings,analyzes the current status of soilification technologies for lead-zinc,copper,gold,and rare earth tailings,discusses the challenges in utilizing soilified non-ferrous metal tailings,and provides a forward-looking perspective to offer a reference for the green and comprehensive utilization of large-scale tailings from non-ferrous metal mines.
