摘要
随着我国工业化进程的推进,钼资源需求量不断增加,钼矿大规模开采导致钼尾矿量与日俱增。钼尾矿的大量堆存,不仅占用宝贵的土地资源,还可能造成土壤重金属污染。钼尾矿中含有多种有价组分,具有资源化利用潜力。本文总结了我国钼矿资源现状,分析了钼尾矿组分特征,综述了钼尾矿中有价组分的回收及其在建筑材料、充填和农业等领域的应用现状。未来,钼尾矿综合利用须重点突破多段浮选工艺优化和药剂降耗等难题,以提升有价组分回收率;同时,通过优化尾矿配比和重金属钝化技术,拓展其应用范围。
With the advancement of China’s industrialization process,the demand for molybdenum resources is increasing,and the large-scale mining of molybdenum ore leads to the increasing amount of molybdenum tailings.The large amount of molybdenum tailings not only occupies valuable land resources,but also may cause soil heavy metal pollution.Molybdenum tailings contain a variety of valuable components and have potential for resource utilization.This paper summarizes the current situation of molybdenum resources in China,analyzes the characteristics of molybdenum tailings components,and summarizes the recovery of valuable components in molybdenum tailings and its application in building materials,filling and agriculture.In the future,the comprehensive utilization of molybdenum tailings should focus on breaking through the problems of multi-stage flotation process optimization and reagent consumption reduction,so as to improve the recovery rate of valuable components.At the same time,by optimizing the tailings ratio and heavy metal passivation technology,its application range is expanded.
