iron ore pelletizing process an overview intechopen

Jul 10, 2017· After drying, pellets undergo firing steps, at which temperatures may reach 1350°C. In these steps, the roasting of all pellets components (ore,limestone, binders, etc.) occurs, liberating chemically bonded water and CO 2. Additionally, the sintering of ore grains also happens, leading to the development of mechanical strength
