Iron Ore an overview ScienceDirect Topics

The molten iron is run off to be cast into moulds of the required shape or into ingots ("pigs") for further processing — hence the names "cast iron" or "pig iron" This is an impure form of iron containing about 4 of carbon along with variable amounts of Si Mn P and S It is hard but notoriously brittle
