Metals are extracted from their ore through chemical reaction. Iron ore is an oxide of iron. The oxygen is removed from the ore by heating carbon with the ore to create molten iron and Carbon Dioxide.
Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

Pyrite is an iron ore, which has the chemical formula FeS2 (Iron (II) Sulfide) The sulfide ion present is S22-
Iron is also found combined with other elements in hundreds of minerals; of greatest importance as iron ore are hematite (ferric oxide, Fe 2 O 3), magnetite (triiron tetroxide, Fe 3 O 4), limonite (hydrated ferric oxide hydroxide, FeO(OH)∙nH 2 O), and siderite (ferrous carbonate, FeCO 3). Igneous rocks average about 5 percent iron content.

Limonite (/ ˈ l aɪ m ə n aɪ t /) 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)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and ...

Question: What is the chemical formula for iron ore? Ores: Ores are rocks that contain enough of a mineral for the extraction of that mineral to be economically viable.
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic. Hematite. 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 Fe2O3.
Taconite, a low-grade siliceous iron ore composed of 20–30 percent magnetite occurring in fine-grained banded iron formations. Taconite is mined primarily in the U.S., in the Mesabi Iron Range in Minnesota and the Marquette Iron Range in Michigan.

Iron is an element, represented by the symbol Fe. There is not technically a "chemical formula" for iron because it is an element.
Ores are those minerals from which metals are extracted commercially and economically. Like Bauxite (Al 2 O 3 2H 2 O) is the ore of Aluminium which contains 50% to 70% of Aluminium Oxide.
Nov 16, 2010· If you look more closely at the chemical make up of both minerals it is clear that magnetite contains a far greater proportion of iron than biotite. In addition to this magnetite is far more common than biotite, easier to mine and the extraction of iron from the ore is …
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
Jan 28, 2012· Magnetite is an iron oxide with the chemical formula Fe 3 O 4 whereas hematite is an iron oxide with the chemical formula Fe 2 O 3. Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. This is the key difference between magnetite and hematite. Moreover, magnetite has higher iron content than ...

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.
