Iron ore - Wikipedia

Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have originated in dying stars that are large enough to collapse or explode as supernovae. Although iron is the fourth-most abundant element i

iron processing - Ores Britannica

Concentrates Upgrading. Crushing and screening are straightforward mechanical operations that do not alter an ore’s composition, but some ores need to be upgraded before smelting. Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore

Iron Ores Article about Iron Ores by The Free Dictionary

Iron ores that contain less than 50 percent iron are usually concentrated (to 60 percent iron) by magnetic separation or gravity dressing. Powdery and sulfurous (> 0.3 percent sulfur) rich ores, as well as beneficiation concentrates, are made into lumps by sintering; so-called pelleted iron ore is made from concentrates. To avoid impairing the quality of the steel or the conditions of smelting, iron ores used in
