  Energy Use in US Steel Manufacturing

  As such, the steel manufacturing process begins by smelting iron ore (Fe 2 O 3 or Fe 3 O 4) in a blast furnace. This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron ...
