PDF Characterization of Fluxed Iron Ore Pellets as Compared

The effect of lime addition in hematite iron ore pellets on its physico-chemical as well as mechanical properties with respect to blast furnace requirement was studied in a laboratory scale with

Influence of Pellet Basicity CaO/SiO 2 on Iron Ore Pellet

The properties of the pellets are therefore largely governed by the form and degree of bonding achieved between ore particles and also by the stability of these bonding phases during the reduction of iron oxides. Hence in production of acid basic and fluxed pellets characterization of the bonding and crystalline phases is of prime
