Process mineralogy properties of stage flotation middlings of Anshan type hematite containing carbonates are analyzed.Through conducting flotation condition test,open-circuit test and closed-circuit test, “one rougher,one cleaner”anionic reverse flotation process flow is selected for separation of this stage flotation middlings.Favorable indexes are obtained with concentrate grade of 56.20%,metal recovery rate of 57.10%,SiO2 content of 8.14% and efficient utilization of stage flotation middlings is materialized.
