In the long-process of iron-making, the pelletizing process is a key step to turn iron ore into pellet (Guo et al. 2017, Purohit et al. 2018). Compared with sinter, pellet exhibits the advantage of lower pollutant and carbon emission. The emission intensities of SO 2, NO x, and CO 2 for pellet are 1/3 ~ 1/2 of those for sinter. Increasing the ...

Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature …
