Pellet - an overview | ScienceDirect Topics

For pellets fluxed with limestone and dolomite, the amount of melt phase was found to increase with increasing basicity, while the FeO content of the silicate melt decreased. The swelling index of the limestone fluxed pellets reached its maximum at approximately 0.6 basicity, which is in good agreement with the observations in Figure 15.23.
