Pig Iron International Iron Metallics Association

OverviewMerchant Pig IronComposition and CharacteristicsBenefits in Steelmaking and Ferrous CastingShipping and Handling of Pig IronPig iron is the product of smelting iron ore (also ilmenite) with a high-carbon fuel and reductant such as coke, usually with limestone as a flux. Charcoal and anthracite are also used as fuel and reductant.Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces.The vast majority of pig iron is produced and consumed within integrated steel mill complexes.
