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 % ... Mar 23, 2020 Herein, the reducibility of the iron ore pellet, sinter, and lump ore in the BF shaft are focused on. The experiments are conducted isothermally with a blast furnace simulator (BFS) hightemperature furnace at four different temperatures (700, 800, 900, and 1000 C) for 300 min.
