Limestone Fluxed Pellets

Influence of flux additives on iron ore oxidized pellets

Six additives, i.e., limestone, lime, magnesite, magnesia, dolomite and light-burned-dolomite, were added for investigating their influences on the pellet quality.

Limestone fluxed pellets are highly porous and therefore very reducible but physically weaker than non-fluxed ones. The CCS distribution (see Fig. 13) is broad and the standard deviation is high for both pellet grades; therefore, the average CCS value alone is not a proper indicator of the mechanical properties of the pellets.

Limestone Addition In Iron Ore Pelletizing

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.
