How is Iron Ore Mined

21112014· Iron ore can be mined from all places in the world but to be commercially viable, the percentage of iron in this iron ore needs to be at least 20% This is because lower iron content in the ore will render all the money and effort exerted in mining the ore from under the surface of the earth a big waste This is why minerals near the surface of the earth and containing as a high percentage of iron are mined for the production of iron Most of the iron ore

Iron Ore: Sedimentary Rock Pictures, Definition & More

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 almost every iron and steel object that we use today

Iron Ore | HowStuffWorks

The majority of Earth's iron, however, exists in iron ore Mined right out of the ground, raw ore is mix of ore proper and loose earth called gangue The ore proper can usually be separated by crushing the raw ore and simply washing away the lighter soil Breaking down the ore proper is more difficult, however, as it is a chemical compound of carbonates, hydrates, oxides, silicates, sulfides and various impurities

Iron ore Wikipedia

Iron ore mining methods vary by the type of ore being mined There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits Banded iron formations Main article: Banded iron formation 21billionyearold rock showing banded iron formation

Underground mining (hard rock) Wikipedia

The ore is mined in horizontal or slightly inclined slices, and then filled with waste rock, sand or tailings Either fill option may be consolidated with concrete or left unconsolidated Cut and fill mining is an expensive but selective method, with the advantages of low ore loss and dilution

Geology, Prospecting and Exploration for Iron Ore

Igneous ores These iron ore deposits are formed by crystallization from liquid rock materials, either as layered type deposits that possibly are the result of crystals of heavy iron bearing minerals settling as they crystallize to form iron rich concentrations, or as deposits which show intrusive relationship with their wall rocks These ore deposits are either tabular or irregular and are composed largely of magnetite with varying amounts of hematite Igneous ores are usually high in iron
