Humic Substance-based Binder In Iron Ore Pelletization:

Due to the reducing ability and bonding effect, a humic substance-based binder has been added into iron ore pellets, both as a reductant and a binder. However, humic substance-based binders were not commonly used in pelletization since some pelletizing results indicated they were not as good asbentonite or other binders. Thus, there were few detailed investigations

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

The limestone addition, i.e. basicity–CaO/SiO 2 of pellet decides the mode, temperature and the amount of melt formed. 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
