Steel is an alloy containing carbon and iron, both of which are abundantly available but seldom found in pure form. In order to make steel from raw materials, iron is obtained from iron ore, which contains plenty of iron oxides. Most of the iron ore in the United States is extracted from taconite, which is abundantly available in Minnesota.

When iron is smelted from its ore, it contains more carbon than is desirable. To become steel, it must be reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. In the past, steel facilities would cast the raw steel product into ingots which would be stored until use in further refinement processes that resulted in the finished product.
