The furnace is fed with iron ore, pellets, and/or sinter, flux and slag producing material such as limestone or dolomite, and coke for fuel. The blast air causes the iron oxides, flux, and coke to react and iron, carbon monoxide and blast-furnace slag is produced.GCSE CHEMISTRY - Extraction of Iron - Haematite - .The calcium silicate (called slag) floats on the liquid iron. Since iron is below carbon in the reactivity series, iron in the ore is reduced to iron metal by heating with carbon (coke). It is actually carbon monoxide which does the reducing in the blast furnace. Links

Coke is cheap and provides both the reducing agent for the reaction and also the heat source. The most commonly used iron ores are hematite, (Fe_2O_3), and magnetite, (Fe_3O_4).Iron Extraction by Blast Furnace Metallurgy - Procedure .Carbon is reacted with Haematite to produce pure iron and carbon monoxide gas which escapes. Fe 2 O 3 +3C = 2Fe + 3 CO After that limestone is added as flux and slag is created. Various impurities like S, Si pass into the slag and later on slag can be easily

Extraction of Iron & Concentration of Ore - An Overview | .

The Haematite then reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas. Fe 2 O 3 +3C→2Fe+3CO Limestone then creates the slag. Impurities such as S, Si pass into the slag and the slag later can be easily separated to yield pure iron.Slag - WikipediaSlag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals.
