Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel and reductant such as coke, usually with limestone as a flux. It is processed further to produce steel or cast iron. It is characterized by its relatively high carbon content and is typically poured into moulds to provide an ingot structure. Pig iron is notably used in the manufacturing of cast iron, as an element in alloy steel production, and in other metallurgical processes. It is often produced in a blast furnace and may be part of a production mix. Availability locations can include 'at plant' for further processing or 'to consumer' for direct applications.
