Understanding the high-grade iron ore market

Magnetite has a slightly higher Fe content as a mineral (7236% vs 6994% for hematite), and its ferromagnetic properties allow for relatively easy concentration using magnetic separation The biggest differentiating factor in terms of value-in-use is the exothermic reaction of magnetite in the sintering and pelletizing processes, saving...
