How it works A blast furnace is used in the process of extracting  iron. The raw materials iron ore, coke and limestone  are put in at the top.  Hot air is blasted into this furnace  at the bottom making the coke (carbon) burn faster and  the temperature rises to about 1500º. When the coke  burns, carbon dioxide is produced.  C + O2 ---> CO2
