How is iron extracted from haematite?
Solution. 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.

25/02/2020 Considering this, is iron ore the same as hematite? Iron (Fe) is a metallic element which constitutes about 5% of the Earth's crust and is the fourth most abundant element in the crust.Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Hematite is an iron oxide mineral.
