Different Types of Iron Ore - 911metallurgist.com

Types of iron ore. The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a 'high-grade' ore, and banded metasedimentary ironstone, magnetite-rich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite which provide a 'low-grade' ore.

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…

Another type of high-grade deposit is pisolitic limonite/goethite ore formed in ancient river channels. One of the primary forms of iron ore is hematite, or iron oxide (Fe2O3). Hematite has in the past been referred to as natural ore because certain hematite ores contain up to 69% iron and can be directly fed into blast furnaces in the steel milling process.
