Hematite is the mineral form of iron (III) oxide (Fe2O3), one of several iron oxides. The name hematite is derived from the Greek word for blood αἷμα haima because hematite can be red, as in rouge, a powdered form of hematite. The color of hematite lends itself to use as a pigment. Hematite is an antiferromagnetic or weakly ferromagnetic.

Three different methods were used for comminution of the low-grade hematite ore: HPGR with an air classifier, HPGR with screening followed by ball milling (HPGR+BM), and cone crushing with screening followed by ball milling (CC+BM). The HPGR test was conducted in a closed circuit, where the final product size was controlled by the air classifier.
