How Is Iron Extracted From the Earth? Reference

Mar 26, 2020· 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.

How is iron obtained from its ore? GridClub

Iron ore consists of the element iron combined with other elements, mostly oxygen. During smelting, the iron ore is heated with carbon. The carbon combines with the oxygen and carries it away, leaving iron. Carbon was originally obtained from charcoal derived from wood, but in the early 1700s furnaces began to use coke derived from coal.
