板石矿业公司选矿厂磨选工艺流程为“阶段磨矿阶段选别、细筛自循环流程”,选矿厂的一段脱水、二段脱水均采用永磁磁力脱水槽。矿物在重力、磁力和上升水流力作用下形成溢流区、分选区和精矿区。在操作过程中,岗位工人只凭肉眼和经验不定期检测精矿层高度及溢流尾矿品位,很难根 Slate Mining Company concentrator milling process for the “stage grinding stage sorting, fine sieve from the recycling process”, a beneficiation plant dehydration, dehydration are used two permanent magnetic dewatering tank. Minerals in the gravity, magnetic force and rising water flow under the formation of overflow area, sorting area and concentrate area. In the process of operation, post-workers only on a non-regular basis with the naked eye and experience testing concentrate height and overflow tailings grade, it is difficult to root
