hematite Definition, Uses, & Facts Britannica

Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for “blood,” in allusion to its red colour. Many of the various forms of hematite have separate names. The steel-gray crystals and coarse

Preparation of Wrought Iron. This is done by heating cast iron with haematite (Fe 2 O 3) which oxidizes C to CO, S to SO 2, Si to SiO 2, P to P 4 O 10 and Mn to MnO. Fe 2 O 3 + 3C → 2Fe + 3CO. Where CO and SO 2 escape, manganous oxides (MnO) and Silica (SiO 2) combine to form slag.. MnO + SiO 2 → MnSiO 3. Similarly phosphorous pentoxide combines with haematite to form ferric phosphate slag.
