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
It should be noted that the removal of oxygen from the iron oxide pellets and lump ores will cause an apparent increase in the percentage of both the iron and the impurities although the relative amount of each remains constant.
