    How is Steel Produced? World Coal Association

    Around 98% of iron ore is used in steel-making. During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities). Air which is heated to about 1200°C is blown into the furnace through nozzles in the lower section. The air causes the coke to burn, producing carbon monoxide which reacts with the iron

    Steelmaking and Refining Introduction to Chemistry
