Preparation of Iron Ore Micro-pellets and Their Effect on Sinter …
2.2 Preparation of Micro-pellets. In the pelletizing phase, the preparation and characterization of green micro-pellets was attempted before sintering process. After homogenization of the sample (iron ore concentrate), the first step was to determine chemistry, size analysis, and specific surface area.

Iron ore pelletization
Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction processes.

Introduction to Iron ore Pellets and Pelletizing processes
Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than …
