Pellet induration at high temperature for its hardening is an energy intensive process. Therefore, in order to reduce the external energy requirement carbonaceous materials are added to supply in-situ energy on induration. In the present study, different carbonaceous materials viz. Jhamacoal, blast furnace flue dust, and coke powder have been added in pelletization of hematite ore fines to reduce the external energy requirement and to utilize the waste carbonaceous materials. It has been observed that green pellets’ properties are within acceptable limits which are not affected by the presence of the carbonaceous material. The cold compressive strength (CCS) of pellets increases with increasing induration temperature. The furnace-cooled pellets show more strength than air-cooling. Blast Furnace flue dust added pellets show highest CCS among other carbonaceous material added in pellets which is 2515 N /pellet at 1280◦C. RI and RDI has also been influenced by the addition of other carbonaceous materials.
