Research on iron recovery from refractory iron mine discarding rocks

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.
