摘　　要：某高硅型有色金属尾矿主要矿物为石英、明矾石、地开石、绢云母和黄铁矿,石英粒度相对较粗,明矾石和地开石在较细粒级富集,明矾石与石英、地开石、绢云母呈浸染状复杂连生。针对该尾矿样品开展了明矾石和石英回收试验研究,采用“脱泥⁃脱硫⁃明矾石浮选”流程得到的明矾石精矿SO_(3)品位20.14%,明矾石浮选尾矿反浮选回收石英,得到SiO_(2)品位96.38%的石英精矿。该流程实现了有色金属尾矿的高效综合利用。The predominant minerals in a kind of high siliceous non ferrous metal tailings include quartz,alunite,dickite,sericite and pyrite.The quartz has relatively coarser grain size,while alumite and dickite are enriched in a relatively finer fraction.Furthermore,alunite,quartz,dickite and sericite minerals are complicatedly disseminated.Herein,tests were conducted to reclaim alunite and quartz therefrom.An alunite concentrate with SO_(3) grade of 20.14% can be obtained by using a process consisting of desliming,desulfurization and alunite flotation.And then,the obtained alunite flotation tailings are subjected to a reverse flotation,yielding a quartz concentrate grading 96.38% SiO_(2).It is shown that this flowsheet can actualize an efficient and comprehensive utilization of nonferrous metal tailings.
