what is the significance of iron ore?
606892
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.

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; 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.

Several species of oxide minerals are also quite useful for industrial purposes, and hold significant economic value. These include chief ores such as Hematite and Magnetite (Iron), Chromite (Chromium), Manganite (Manganese), Cassiterite (Tin), Ilmenite and Rutile (Titanium), Franklinite and Zincite (Zinc).

Iron is mineral that can be found in plants, animals, soil, air, water, meteorites, and rocks, including ones found on the surface of the moon. ... Iron is a metal; in fact, people with too much iron in their bodies can set off metal detectors.

Iron (ferrous fumarate, ferrous gluconate, ferrous sulfate) is used to treat or prevent anemia (a lower than normal number of red blood cells) when the amount of iron taken in from the diet is not enough. Iron is a mineral that is available as a dietary supplement.

Pellets are small balls of iron ore used in the production of steel. They are made with technology that uses the powder that is generated during the ore extraction process, once considered waste.

Currently magnetite iron ore is mined in Minnesota and Michigan in the U.S., Eastern Canada and Northern Sweden. Magnetite-bearing banded iron formation is currently mined extensively in Brazil, which exports significant quantities to Asia, and there is a nascent and large magnetite iron-ore industry in Australia.

Pig iron is the product of smelting iron ore (also ilmenite) with a high-carbon fuel and reductant such as coke, usually with limestone as a flux. ... Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces.

A hot rock can loosely be defined as: any rock or stone not containing a valuable mineral (gold, silver, or copper) which generates an audible signal response on a metal detector. ... These minerals are predominately the iron oxides: magnetite, hematite, limonite, maghemite and lepidocrocite.
