The article considers mineralogical and technological features of ferruginous quartzites in the Zaimandrovsky region?s deposits and tailings from the rough magnetic separation. A technology has been developed for the stadial separation of magnetite concentrate from the initial ore, including the ore preparation, magnetic separation, and also the joint use of fine screening and magnetic gravity separation. The increase in the efficiency of the gravitational cycle for the hematite concentrate production was achieved...
