role of limestone in iron ore pellet making

influence of pellet basicity cao sio 2 on iron ore

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
