Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.
The taconite pellets are brought to the steel mills to be melted down into steel. Taconite is mined from the Mesabi Iron Range, near Hibbing, MN. Then it is processed into pellets and moved by train--or on ore boats from Duluth--to ports and steel mills around the Great Lakes region.
What is Iron Ore Used For? The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods .
