Mining of Iron from iron ore is done most commonly by blast furnace method. The smelting process allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away leaving behind iron. Blast furnaces are so hot which is why they melt the iron and drain it off to be poured into moulds to form bars called ingots. all the operations to be mechanized and mining is
