Raw materials
The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an open-grained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore …

Raw materials
To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of 'stealing' the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c.
