The iron ore processing industry produces usable concentrations of ironbearing material by removing nonferrous rock (gangue) from lowgrade ore. In the United States, predominant iron ore is taconite which is a hard, banded, lowgrade ore. Ninetynine percent of the crude iron ore produced in the United States is taconite.

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
