How Is Iron Obtained? Reference

Iron is obtained by extracting it from iron ore in a large container, called a blast furnace. The blast furnace is necessary to smelt the iron out of the ore. Smelting is a process in which the iron ore is heated until it becomes spongy and the chemicals in the ore begin to break down.

Iron ore - Wikipedia

  

2019-10-15  Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.

How Is Iron Extracted From the Earth? Reference

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
