Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3).

Most iron is found in minerals formed by the combination of iron with other elements. Iron oxides are the most common. Those minerals near the surface of the earth that have the highest iron content are known as iron ores and are mined commercially. Iron ore is converted into various types of

Only at the earths surface or in the present of oxidizing fluids does iron 2+ form iron 3+ as an oxide mineral like hematite. Furthermore, iron oxidation via photosynthecially created o2 isn't the only pathway to form iron oxides. For example, photochemical dissociation can do it as well, which is the likely reason why iron on Mars is oxidized.

Iron ores are rocks and minerals rich in iron oxide that can produce metallic iron when smelted. Due to the nature of the iron oxide present in iron ore, they can range in color from dark grey to a deep red. The iron in such ores is commonly found in the form of magnetite, hematite, goethite, limonite, and siderite.

The iron ore deposits are found in sedimentary rocks. They are formed by the chemical reaction of iron and oxygen mixed in the marine and fresh water. The important iron oxides in these deposits are hematite and magnetite. These are ores from where iron is extracted.

It melts at a temperature of 1,538° C (2,800° F). Iron is allotropic—that is, it exists in different forms. Its crystal structure is either body-centred cubic (bcc) or face-centred cubic (fcc), depending on the temperature. In both crystallographic modifications, the basic configuration is a cube with iron atoms located at the corners.

In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite (FeO (OH)). Iron-bearing groundwater typically emerges as a spring. The iron is oxidized to ferric hydroxide upon encountering the oxidizing environment of the surface. Bog ore often combines goethite, magnetite, and vugs or

The historic period known as the Iron Age began in south-central Asia, replacing what had been the key metal, bronze. Civilizations learned that iron, when mixed with carbon, is more durable than bronze. Iron weapons also hold a sharper edge. Ancestor of Steel. Iron continued as the key metal fabric in human civilization until the 1850s, when innovators began to learn that if a bit more carbon

Iron ore may be shipped in a number of forms: ROM : run of mine, which is ore as it comes from the mine, of no particular grade; Fines : small screenings of ore (less than 6mm). Fines may be sintered to form large particles, lumps or masses by heating the material to below its melting point with another material (e.g. limestone or coke breeze) until its particles adhere together.

To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores.
