Abstract :

Iron ore are used to extract iron. For effective extraction process, the ore is subjected to agglomeration. Pelletizing is the one most commonly used agglomeration method in the world. Normally pellets are prepared using iron ore, binder and coke or coal. Sawdust is a waste product of the furniture industry. Teak wood and mahogany wood sawdust are widely available in Sri Lanka. In this study, teak sawdust was used to obtain porosity in pellets instead of coke. It is a combustible material at lower temperatures of approximately 200 ̊C. The effect of sawdust was studied on the compressive strength, porosity and reducibility of the prepared pellets. By this study it was found that lower amounts of sawdust with high sintering temperature gives the optimized properties for the pellets prepared with Dela iron ore.
