Firstly, the raw hematite ores are evenly sent to a jaw crusher through a vibrating feeder for coarse crushing, then are sent to a cone crusher for fine crushing. Next, the ore is screened by a vibrating screen. Those whose particle size meet the requirements would be sent for grinding, while the others would return the cone c…

The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
