Reduction procedure. Industrially iron is produced from iron ores, principally hematite (Fe 2 O 3), magnetite (Fe 3 O 4) by a carbothermic reaction that is reduction with carbon, in a blast furnace at temperatures about 800–1,600°C.In the blast furnace, iron ore, carbon in the form of coke, and a flux such as limestone are fed into the top of the …
