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 SO3 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% SiO2. It is shown that this flowsheet can actualize an efficient and comprehensive utilization of nonferrous metal tailings.
