  • What is the use of limestone of in the extraction of iron

    Limestone is used in iron extraction to remove impurities from the iron and becomes molten slag. The calcium carbonate (CaO3) in limestone catabolically 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 with impure iron such as iron sulfide(FeS).

  • Creating Iron HowStuffWorks

    A blast furnace is charged with iron ore charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace and the calcium in the limestone combines with the silicates to form slag. Liquid iron collects at the bottom of the blast furnace underneath a layer of slag.
