Effect of fluxing agents on reduction degradation

In limestone fluxed pellets, reduction degradation index dropped considerably with increasing CaO content due to the formation of more amount of bonding phase. Dolomite–pyroxenite pellets, on the other hand, showed lower reduction degradation index up to 0.4 basicity, and beyond that, higher degradation was observed due to the increased pore ...

limestone addition in iron ore pelletizing

effect of limestone binder in iron ore pellets. The term iron ore pellets refers to the thermally agglomerated substance formed by heating a variable mixture of iron ore, limestone, olivine, bentonite, dolomite and miscellaneous iron bearing materials in the range of 1250 deg C to 1350 deg C. Iron ore pellets are normally produced in two types of grades namely DRI grade and BF grade.
