Difference Between Magnetite and Hematite

EtymologyCharacteristicsChemistryPropertiesDistributionSignificanceResourcesSourcesMagnetite is an iron oxide with the chemical formula Fe3O4. Actually, it is a mixture of two iron oxides, FeO and Fe2O3. Therefore, we can show it as FeOFe2O3. According to the IUPAC nomenclature, its name is iron (II, III) oxide. But, commonly we name this as ferrous-ferric oxide. Magnetite got its name because it is a magnet.

Why we use hematite over magnetite as iron ore? - Quora

May 09, 2018  The structure of hematite is hexagonal and that of magnetite is BCT or inverse spinel. During reduction, the phase change in hematite takes place at a temperature of 500 deg C. This change brings with it an increase in the volume thereby increasin

Hematite - Wikipedia

Hematite is colored black to steel or silver-gray, brown to reddish-brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more
