How Is Iron Extracted From the Earth? - Reference.com

26-03-2020· 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.

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

Raw materials in the Steel Industry

Iron ore: It is found in the Earth's crust, in its oxidized form, as magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe, etc. These compounds contain high iron content per unit mass, and can directly be fed into a blast furnace for further mechanisms. Approximately 1.5 tonnes of iron ore is processed, to make 1 ton of pig-iron.
