Iron ore
Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km (620 mi) in diameter or larger The origin of iron can be ultimately traced to the formation through nuclear fusion in stars, and most of the iron is thought to haOres Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed Iron processing Ores, Smelting, Refining Britannica

Iron mining in the United States
Iron mining in the United States produced 48 million metric tons of iron ore in 2019. None of the iron ore now mined in the US is “direct shipping” ore ready to be fed into the Iron is a common metal found in the earth's crust, where it occurs in combination with other elements. The term "iron ore" is used when the rock is sufficiently rich in iron minerals to be mined economically. Iron ore yields metallic iron (Fe) when heated in the presence of a reducing agent such as coke. Iron ore usually consists of Iron Ore The Canadian Encyclopedia

Iron Ore Statistics and Information U.S. Geological Survey
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.

Iron Ore Geoscience Australia
Download. Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.Crushing, a form of comminution, one of the unit operations of mineral processing. In the field of extractive metallurgy, mineral processing is the process of separating commercially valuable minerals from their ores.

A short review on environmental impacts and application of iron ore
Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature, especially during the different stages of its extraction and production. The improper disposal of such waste causes negative impact on the environment. One such waste which is generated during the beneficiation process of Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, classification etc., but the advantage is only partial removal Mining of Iron Ores IspatGuru
