阶段磨选流程应用磁选柱既抛尾又拿精的探讨

Discussion on the Application of Magnetic Separation Column in Stage Grinding separation Flowsheet for Both Tailings Rejection and Concentrate Collection

介绍了磁铁矿选厂现行阶段磨细筛自循环磁选流程和细筛再磨磁选流程的优缺点，在此基础上，探讨了在阶段磨选流程中引入磁选柱，实现单一磁选法阶段抛尾、阶段拿精的可行性。

The merits and demerits of the stage grinding fine screening self circulating magnetic separation flowsheet and the fine screening regrinding magnetic separation flowsheet currently used in the magnetite ore concentrators.On this basis,the feasibility of introducing magnetic separation column into the stage grinding concentration flowsheet to realize tailings rejection and concentrate collection in single magnetic separation stage is discussed.
