Why iron ore is pelletized? AnswersToAll

01/03/2021 Pelletizing of iron ore Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. This is the reason that iron ore is preferred in the form of pellets rather than in the form of finer particles. How are steel pellets made? Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These
