Ironmaking 101 – From Ore to Iron with Blast Furnaces ...

10/10/2017  Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) 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. The iron ore is dressed or crushed into 0.5-1 in. chunks ...

What is Smelting?, and Iron ore Smelting process ...

Iron smelting involves two main processes in the blast furnace: (1) the reduction of iron from it compounds and (2) its separation from its physical mixture with gangue materials. In furnace, the charge is constantly moving slowing downward against the force flow of the very hot gases which bring about the evaporation of moisture from the charge at the top.

Corex Process - Wikipedia

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 up to 80% lump ore and uses non coking coal directly as a reducing agent.

HOW A BLAST FURNACE WORKS - Foundry Gate

a blast furnace without any further processing. Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content. Pellets are produced from this lower iron content ore. This ore is crushed and ground into a powder so the waste material called gangue can be removed. The remaining iron-rich powder is rolled into balls and fired in a furnace to produce ...
