Iron Ore hematite Iron ore Magnetite Iron ore Iron ore Fines, Lumps and Pellets. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red.
Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron.
Iron Ore is a kind of ore that becomes the material of Iron. It is a mineral that contains Iron (Fe) and there are several types of it. Main kinds of Iron Ore are listed below. 1. Hematite 2. Magnetite 3. Goethite 4. Lepidocrocite 5. Limonite 6. Siderite 7. Iron Sand Iron Sand is an aggregate of weathered Magnetite.
Metallic Iron is most commonly produced from the smelting of iron ore to produce pig iron. Iron ore is in the form of rock and vary in color from dark grey to rusty red and is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3) which is also called natural ore , limonite or siderite. Siderite is a mineral composed of Iron.
The most important iron minerals are magnetite, magnesioferrite, titanomagnetite, hematite, hydrohematite, goethite, hydrogoethite, siderite, and iron chlorites (chamosite, thuringite, and others). The iron content of industrial ores varies within wide limits, from 16 to 70 percent.
