    Nov 11, 2017· Magnetite has higher iron content thanhematite. But hematite ore usually contains large concentrations of hematite; magnetite ore, low concentrations of magnetite. The ore has lower iron content, typically between 25% and 40% Fe. This ore is unsuitable for steel making, and it must be concentrated before it can be used to produce steel.
