iron-bearing tailings using magnetizing roasting followed by magnetic separation. Sep. Sci.A joint process of flotation and magnetic separation was proposed to process the ore. This paper introduces the test results of flotation tailings by a wet drum separator. Results show that iron concentrate assaying 60.21-68.12% Fe at a recovery of 71.9-75.32% can be obtained,
