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 sinter ...

pelletization process by Kshirod - SlideShare

The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during smelting. This is the reason that iron ore is referred in the form of pellets rather than in the form of finer particles. 3.

WELSPUN STEEL LIMITED

Iron Ore: In sponge iron making, iron ore is reduced in solid state. Unlike in the conventional steel melting processes, the gangue content of iron ore cannot be separated as a slag. Therefore, it becomes imperative to select an ore with a high Fe content and a low gangue content, to optimize yield during steel making.
