Jessica Ellis Pig iron begins with iron ore and other raw materials. Pig iron is a metal material that results when iron ore, charcoal from coal, and limestone are melted together under intense air pressure.When the combined material cools, it forms a high-carbon product known as pig iron.The cooled material is rarely used by itself, as the large amount of carbon makes the material brittle and ...
