Options to resolve the issue include ramping up the mining of higher-grade ores, concentrating the iron in lower-quality ores or advancements in green steelmaking technology that would enable the use of lower-iron ore. Iron ore miners could also pivot from hematite ores toward magnetite ores. While magnetite tends to have lower iron content ...
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, …

The possible value of the red hematite iron ore of the southern Appalachian States, if some practicable method of concentrating it could be devised, has long been recognized. The ore is very low grade, and although in enormous quantities, particularly in the States of Alabama, Tennessee, and Georgia, is only at a few points rich enough to work, and even the best of it …
A Lake Superior district hematite ore concentrating facility has been effectively using selective flocculation and dispersion for concentrating hematite ore bodies since 1974. Selective flocculation is the process of choice because of the relatively non-magnetic nature and small liberation size (< 25 μm) of the iron minerals ( Paananen and ...
