The iron ore beneficiation process aims to remove impurities and enhance the iron content in the ore, making it suitable for use in steel production. Iron ore beneficiation Process. Limonite Beneficiation. Because the theoretical iron grade of limonite is low, and often with calcium and magnesium, manganese is a homogeneous …

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 %).
