The Direct Reduction of Iron Ore
The iron ore from which iron and steel are made is an oxide, that is, a chemi cal compound of iron (Fe) and oxy gen (0). Common forms of ore are hematite (Fe20a) and magnetite (Fea04)' For the ore to be made into iron the oxygen atoms must be separated from the iron atoms by the process known as reduction. The separation

Creating Steel | HowStuffWorks
The advantage of steel over iron is greatly improved strength. The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface.

The Era of Pig Iron in the Upper Peninsula of Michigan-Fall 1969
In 1870 the industry supplied the nation with 20 percent of its pig iron. Among producers of charcoal iron Michigan ranked second in 1870, and the census of 1880 reported Michigan as the foremost producer of charcoal pig irons. 8 By then, however, charcoal iron was rapidly losing its markets to the steel industry.
