Ironmaking 101 – From Ore to Iron with Blast …
Ironmaking Blast Furnace Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.
Blast furnace | metallurgy | Britannica
Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals. Rapid combustion is maintained by the current of air under pressure. A zinc-lead blast furnace and lead-splash condenser.
Blast Furnace - an overview | ScienceDirect Topics
As an alternative to iron production in a blast furnace, direct-reduced iron (DRI) is produced by reducing iron ore using a mixture of hydrogen and carbon monoxide (Reaction (5.7) and (5.9)) at temperatures of 800–1000°C.

Blast furnace process - tec-science
A further lowering of the iron ores in the blast furnace leads to the temperature zone of 400 °C to 800 °C. In this region, the so-called indirect reduction of iron ores to iron by carbon monoxide takes place. The carbon monoxide gas (C O) is oxidized to carbon dioxide (C O 2) by absorbing the oxygen contained in the iron oxide (O).
Iron processing - Iron making | Britannica
The primary objective of iron making is to release iron from stone combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
Iron Ore Process From The Blast Furance

Corex Process - Wikipedia
Process. The Corex process consists of two main parts a Reduction Shaft and a Melter- Gasifier.The main reagents for the Corex process are iron ore, noncoking coal, and oxygen. Unlike the Blast furnace the Corex process does not use a hot blast of nitrogen, thereby greatly reducing NOx gas emissions, but instead uses oxygen. In addition, the Corex process can use iron oxides containing …
