How is Iron Extracted from Iron Ore | Actforlibraries

Iron is an element that has the chemical symbol, Fe. It is a metal that has been used since prehistory, by the Ancient Egyptians and Sumerians as early as 4000 B.C. These ancient peoples were able to get pure iron from meteorites that fell to the earth, and they used it in the tips of weapons and spears because of its strength and durability.

Ore Mineral

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45) on ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.
