How Is Iron Extracted From the Earth?
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

Electric mining drill
The electric mining drill mines out iron ore, copper ore, uranium ore, stone and coal, and places it in front of the output tile, on a belt or in a machine or chest that covers the output tile.. The machine is 3×3, but mines in a 5×5 area, extending 1 tile away on each side. Mines copper ore, iron ore, coal, or stone at a rate of 0.5/s and uranium ore at a rate of 0.25/s.

Iron Ore: Sedimentary Rock
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

How was iron smelted 3,000 years ago? Researchers rebuild
The Iron Age was a turning point in the history of the Land of Israel. Iron tools began to appear around 3,000 years ago, gradually supplanting the softer copper and bronze tools. It was also a time of dramatic political change, as the Hebrew kingdoms, Judah and Israel began to take shape, which may or may not have to do with the advent of iron.

How is Steel Made? | Metal Casting Blog
At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called “pig iron.”. Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron.

Iron Ore Smelting Process
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being
