| Abstract: | 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. |
