    The iron ore itself is not pure ore. It is also contaminated with a variety of rock, which will not necessarily melt at blast furnace temperatures and therefore could clog it up. For this reason, limestone, or calcium carbonate, is added to the initial furnace charge. The hot furnace reacts with the limestone to give calcium oxide. CaCO3 → CaO + CO2. This reaction is endothermic, and it ...
