This paper reported effects of lime powder and bentonite binder using in iron ore pelletization on metallurgical properties of pellets as green strength, compressive strength and degree of reduction. The investigated pellets contain 0, 1 and 2 mass % of lime powder and 2, 1 and 0 mass % of bentonite, respectively. Green balls were dried (105 °c for 24 hours) then heated at 1200 °c for 30 minutes. The reductibility of fired pellets was examined at different temperatures of 900, 1000 and 1100 °c with various holding time (45, 90 and 120 minutes). The results showed that the combination of 1 mass % of bentonite and 1 mass % of lime powder in the pellet gave the most apropriate metallurgical properties of pellets as green strength, porosity and degree of reduction. This material charging ratio can be recommended for application in manufacturing of the pellet.
