Utilization of iron bearing dusts has been needed agglomeration prior to use as a burden in blast furnace The cold bonded pellet process using iron bearing dusts has been developed as an alternative to the conventional heat indurated pelletizing process. Partial substitution of cements with cheaper materials would decrease the production cost of pellet. This paper discusses the strength of pellet containing blast furnace slag as a bonding material in pelletizing a cold bonded agglomerates. Depending upon the quality, half of the cement required may be replaced by slag in the pellets with a strength of around 150 kgf. Some of the physicochemical properties of the bonding materials are also investigated in the present work.
