The only source of primary iron is iron ore. The USGS defines iron ore as 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). It''s a major ingredient in steel. Here''s

Hematite is a steelgray to iron black colored mineral which is as hard as magnetite (Moh''s scale hardness is 5.5 to 6.5) but slightly less heavy (usually specific gravity varies from 5.0 to 5.3). It has also a metallic luster. The three primary sources of iron ore are banded iron formations, magmatic magnetite ore deposits, and hematite ore.

In hematite ore processing plant, the crushing technology contains several processes, including feeding, primary hematite ore crushing, secondary crushing
Where an ore is defined as a naturally occurring solid material from which a metal can be extracted profitably, then the finest quality ore would be meteoric iron, where the iron is already elemental and at high purity. Image courtesy Iron meteori
Metallic minerals are minerals that have a metallic luster, making them very shiny. A few metallic minerals are Graphite, Galena, Magnetite, and Pyrite. The mineral Hematite can be metallic or
Hematite (Fe 2 O 3) is an iron oxide mineral.It is widespread in nature, especially in sedimentary environments. Hematite is one of the two principal iron ores. The other is magnetite, which is also an iron oxide mineral.The term ''hematite'' itself might not be familiar

Hematite is a primary component of ordinary rust, but the porousity, softness, and flakyness of rust is likely due to goethite. The beautiful iridescent coating sometimes found on hematite is due to Turgite, still another "not really a" mineral composed of a mixture of hematite and goethite and sometimes described as being a hydrated hematite.
With all of hematite''s many varieties, it is natural that some of them can be easily confused with other metallic minerals. All of the hematite varieties though, exhibit the same distinctive red to redbrown streak when scratched across a rough hard surface, which should serve to distinguish hematite from similarappearing minerals.
Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.. The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost
