    Influence Of Pellet Basicity (cao Sio2) On Iron Ore Pellet

    Characteristics of iron ore itself Generally the higher iron content of pellets have the higher reducibility and the higher clustering tendency Remark Addition of lime (hydrated lime or limestone) and or dolomite to iron ore results in lower clustering tendency of pellets and higher compression strength of sponge iron e) Reducibility.Iron Ore Pellets are formed from beneficiated or run of mine iron fines The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent.
