There are certain differences between hematite concentrates and magnetite concentrates; plants may be optimised to use one over the other. Magnetite has a slightly higher Fe content as a mineral (72.36% vs 69.94% for hematite), and its ferromagnetic properties allow for relatively easy concentration using magnetic separation.

Banded hematite quartzite (BHQ) and banded hematite jasper (BHJ) ores represent a promising potential iron ore resource in the near future. The hematite and quartz in BHQ and the hematite and jasper in BHJ are closely related and require fine grinding for the liberation of hematite phases. The present study investigates the mineralogical features and comminution …
