    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, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known

    Impurities in Iron OresIron Ore FormationOrigin of Iron Ore-BodiesMagnetiteLimoniteSideriteThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel-making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so-called Bessemer...

    Figure 9.8 presents a typical flow sheet for processing a magnetite ore using multiple stages of low-intensity magnetic drum separators. The ore consists predominantly of magnetite and quartz. There are three stages of ball mill grinding and magnetic separation, using low-intensity magnetic drum separators to reject quartz as early as possible.

  • Iron-Oxide Concretions and Nodules, 1 Some Meteorite

    Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people’s attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.

  • Iron Ore Statistics and Information USGS

    Iron ore is 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 (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.

  • Magnetite an overview ScienceDirect Topics

    Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral, and not only because it is magnetic.The formula could be written as Fe 2+ Fe 3+ 2O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2+) and ferric (Fe 3+) ions implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

  • Iron processing Ores Britannica

    The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe 2 O 3), which is red; magnetite (Fe 3 O 4), which is black; limonite or bog-iron ore (2Fe 2 O 3 ·3H 2 O), which is brown; and siderite (FeCO 3), which is pale brown. Hematite and magnetite are by far the most common types of ore.
