摘要
云南是矿产资源大省,矿石储量丰富,其矿石资源主要赋存于寒武系地层中。前期矿石资源采用擦洗回收,回收率低,尾矿品位较高,随着资源的日益枯竭及选矿工艺成熟,尾矿回收利用既能资源化,也能减少占用土地。分析研究矿石尾砂有用组分富集特征,对矿石尾砂资源化具有重要意义。
Yunnan is a province with large mineral resources,rich in ore reserves,and its ore resources mainly occur in Cambrian strata.In the early stage,the ore resources are recovered by scrubbing,with low recovery rate and high tailings grade.With the increasing depletion of resources and the maturity of beneficiation process,the tailings can be recycled as resources and reduce land occupation.It is of great significance to analyze and study the enrichment characteristics of useful components of ore tailings for resource utilization of ore tailings.
