effect of lime addition on iron ore pelletization

  • The Effect of Lime Addition on Reduction of Iron Ore Pellets

    For the commercial production of iron ore pellets from hematite ores, as it is practiced in various pellet plants, the addition of lime has shown to be an efficient means with a view to improving cold compression and abrasive strength of the indurated pellets considerably.

    addition of 20% of LKAB iron ore concentrate to the sinter blend, has no significant impact on productivity. On the other hand, addition of 20% pellet screenings prove to have a positive effect compared to the reference case. From the results, the addition of 20% pellet screenings increase the productivity by slightly more than 7%.

  • Pelletization

    1-1-2012The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization: The binder makes the moist ore plastic, so that it will nucleate seeds that grow at a controlled rate into well-formed pellets.
