 · Abstract: 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.

 · Iron ore must be shipped in bulk for maximum economy. 1.2 Pretreatment process In this process, the iron ore is ground into fines having qualities required for the subsequent balling process. The pretreatment includes concentrating, dewatering, grinding, drying and prewetting. In general, low-grade iron ore is ground into fines

Pelletization is the process of transforming iron ore fines into spherical pellets through agglomeration and induration.
