摘　　要：本文对某选厂的抛尾废石采用阶段磨矿,阶段选别工艺进行回收,最终可获得产率为1.21%、品位为60.05%、回收率为4.12%的铁精矿,以及产率为39.55%、品位为30.31%、回收率为68.00%的中矿。为选矿厂抛尾废石的利用,提供了一条可行的途径。This paper adopts phase ore grinding and phase sorting craft to recover iron from Discarding rocks. At last we get the iron concentrate with the indexes of productivity 1.21%, grade 60.05%, recovery 4. 12%. In the meantime, we get middling product with the indexes of productivity 39.55%, grade 30.31%, recovery 68.00%. It provides a feasible approach of using discarding rocks.
