The furnace is charged from the top with a mixture of iron ore, coke, and limestone (Figure 29.8). A strong (about 350 mph) blast of preheated air (or oxygen) is blown in at the bottom, where the coke burns to carbon monoxide, which is the reducing agent. The charge is heated gradually as it descends. First the moisture is driven off.

COREX is a coal-based hot metal process. The process basically consists of two reactors: a reduction shaft and a melter/gasifier reactor. Lump iron ore, sinter, and/or pellets are reduced by first being metallized in a reduction shaft by off-gases coming from the melter/gasifier reactor. The product consists of approximately 90% reduced iron.

Haematite and magnetite are the most commonly found iron ore minerals. The smelting process allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away, leaving behind iron. Blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots.
