Pig iron is an intermediate product of the iron industry, also known as crude iron, which is first obtained from a smelting furnace in the form of oblong blocks. Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.

The direct production of steel from iron ore in the electric furnace has never passed beyond the laboratory stage. Just as pig iron can be produced from iron ore in the electric furnace, so can pig steel be produced by a close regulation of the carbon content of the charge.
Iron Ore Processing for the Blast Furnace (Courtesy of the National Steel Pellet Company) The following describes operations at the National Steel Pellet Company, an iron ore mining and processing facility located on the Mesabi Iron Range of Minnesota. Creating steel from low-grade iron ore requires a long process of mining, crushing,
A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made.
