Iron does not occur in nature as a pure substance but as a compound in rocks, which can contain up to 50 % iron. These ferrous rocks are also called iron ores. The iron compounds contained therein are mainly iron oxides, but also iron carbonates or iron sulphides. The most important iron oxides include: magnetite: \(Fe_3O_4\) hematite (haematite): \(Fe_2O_3\) siderite,How is Iron Extracted from Iron Ore | Actforlibraries.org,The iron ore itself is not pure ore. It is also contaminated with a variety of rock, which will not necessarily melt at blast furnace temperatures and therefore could clog it up. For this reason, limestone, or calcium carbonate, is added to the initial furnace charge. The hot furnace reacts with the limestone to give calcium oxide. CaCO3 → CaO + CO2.
