    Jan 9, 2017 Limestone is used in iron extraction to remove impurities from the iron and becomes molten slag. The calcium carbonate (CaO3) in limestone abolically reacts, forming calcium oxide(CaO) and carbon dioxide(CO2). CaO is highly reactive when subjected to the extreme heat of the furnace. CaO can react
