Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries.

Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.

Hematite is an ore of iron, a midvalue metal useful for weapons, armor, and steel production.

Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world.

Jun 30, 2019· Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.

Jan 18, 2016· 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 increasing the porosity and increased indirect reduction due to the rising CO gases.

Hematite Hematite has a long history of use as a pigment. As a gemstone, this material is often carved but very rarely faceted. Despite its association with blood and the color red, hematite's color can range from black and metallic gray to brownish red in thin slivers or crystals.
