Iron ore extraction. 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)

How is iron extracted from haematite? Medium Solution Verified by Toppr Iron is extracted from its ore, haematite in a blast furnace. The ore is led into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.

Why is limestone added in the extraction of iron? The main function of limestone in the extraction of iron from haematite is as a flux. Limestone is used as a flux to remove the impurities and dirt from haematite. Limestone decomposes in a hot furnace and forms calcium oxide (CaO). Iron is extracted from its ore, haematite, in a blast furnace.
