What Is the Process of Manufacturing Iron Ore Pellets? Pellets are formed using a method called Pellitizing. In this method, finely powdered grains of iron ore are converted into balls. These balls usually have a proportion (8mm to 20mm) that is strictly adhered to during the manufacturing process. These pellets are then used in the blast ...
