Why is coke added to the blast furnace Publisher Summary Metallurgical coke along with iron ore and limestone is layered into a blast furnace to convert the iron ore to metallic which is mostly carbon reacts with the blast air to produce carbon monoxide which in turn reacts with the iron oxide to produce carbon dioxide and metallic iron

Dec 11 2021The extraction of iron from its ores is quite a technical process The iron ore is first roasted in air to produce iron III oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres
