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 opengrained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.
