The main source of heat in the iron extraction process in a blast furnace is **Coke**.

Coke is a carbon-rich material derived from the heating of coal in the absence of air, known as carbonization. It serves multiple important functions in the blast furnace operation. First, it acts as a fuel that combusts with the hot air that is blown in from the bottom of the furnace, generating the necessary heat to reach the high temperatures required for iron extraction, which can exceed 1500°C.

Secondly, the combustion of coke produces carbon monoxide, a reducing agent that helps in reducing iron oxides (like hematite, Fe₂O₃, and magnetite, Fe₃O₄) to produce molten iron. The use of coke significantly enhances the efficiency of the iron production process by providing both the thermal energy and the reducing power. Consequently, coke is essential not only as a heat source but also in the chemical reactions involved in the extraction of iron from its ores.
