Limestone is the reducing agent, without limestone the iron ore Fe2O3 will never get reduced to Pig iron Fe .. "calcination" should be lesser inside the blast furnace to reduce the coke rate that's why sinter is being used nowadays, as in sintering process limestone is calcinised outside the furnace which reduces the coke rate by 5–8%.

the sinter. In the sintering process, the iron ore corresponds to the mixture of hematite, goethite and other gangue mineral typologies. However the goethite and gangue contents are relatively lower than the hematite, but the goethite + gangue to hematite ratio influences the reactivity during sintering. The minerals association in iron
