Ironmaking 101 From Ore to Iron with Blast Furnaces

Ironmaking 101 From Ore to Iron with Blast Furnaces

Oct 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. Metallization or the degree of reduction of the pellet has an impact on the energy consumption of the EAF steelmaking furnace. DRI metallization is defined as the percentage of metallic iron in the reduced pellet divided by the total iron in the reduced pellet. ...
