Extraction of Iron ore. Iron is extracted from its ore in the blast furnace. The main iron ore is called hematite. Hematite is iron (III) oxide - Fe2O3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace.
