Introduction to Iron ore Pellets and Pelletizing processes
The various advantages of iron ore pellets are given below. 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 %).

THE POTENTIAL OF PELLETIZING FOR IRON ORE …
To enrich the iron ore, it is necessary to comminute the ore to the flotation fineness and to feed it to sorting processes such as magnetic separation and flotation. The resulting iron ore concentrate is then used with binders, e.g. bentonite or organic binders such as carboxymethyl cellulose and polyacrylamide in the disc.
