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 limit. A Bessemer ore carrying 52% of iron must not have more than .052% of phosphorus and the sulphur should not exceed .04%.
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. Although it was once mined ...
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks ...

Details of the common iron ore and associated gangue minerals found in many iron ore deposits and iron ore products are given in Table 2.1.The three most common iron ore minerals are magnetite, hematite (the spelling "hematite" is preferred here over "haematite"), and goethite, which together account for an estimated > 99% of the iron minerals contained in world seaborne-traded iron ...
What is Iron Ore? Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). These iron ores have been mined to produce ...
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...
In 2014, one U.S. company mined chromite ore in Oregon from which it produced foundry sand. Imported chromite ore was consumed by one chemical firm to produce chromium chemicals ... Import Sources (2010-13): Chromite mineral: South Africa, .
Introduction. The production of iron from its ore involves a redox reaction carried out in a blast furnace. The furnace is filled at the top with the iron ore oxide most commonly hematite ((Fe_2O_3)) but can also magnetite ((Fe_3O_4)), carbon called coke and limestone ((CaCO_3)).

Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...
The world's resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.

Limonite is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)
Magnetite (Fe 3 O 4) is a common iron ore mineral in iron ore deposits of metasedimentary and magmatic origin. Magnetite has an inverse spinel structure and is partly altered in near-surface environments to hematite or kenomagnetite (Waychunas, 1991).
Iron is an element, represented by the symbol Fe. There is not technically a "chemical formula" for iron because it is an element.
Figure 1 shows the Fe and gangue contents in the iron ores from different deposits of the major iron ore producing nations and from Muko deposit of Uganda. In this figure, the total gangue content was determined as the sum of SiO 2 and Al 2 O 3 contents in iron ores. All the iron ores were divided into three groups according to the total Fe and gangue content.
Iron(III) oxide is one of the two major iron oxides. It has the chemical formula Fe 2 O 3 and is reddish-brown in color, which makes it useful in pigments for cosmetics and paints.

Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
