The process is demonstrated and explained below: Diagram showing the carbon extraction of iron The raw materials: iron ore (hematite), coke (an impure form of carbon), and limestone are added into the top of the blast furnace Hot air is blown into the bottom Zone 1: Coke burns in the hot air forming carbon dioxide
Moreover, carbon and basicity were optimized as 1.2% and 0.3, respectively, for the same ore in our earlier studies (Ayyandurai and Pal 2021;Pal et al. 2014).
