Abstract :

Dela iron ore, coconut shell charcoal and Aruwakkalu lime are some of the raw material resources in Sri Lanka for iron making. However, proven reserves of iron ore deposits in Sri Lanka have not been scientifically estimated as yet. There is no indication of the occurrence of coal deposits in Sri Lanka for the utilization to produce iron using the blast furnace. Therefore, it is important to investigate the possibility of producing high quality iron ore pellets using locally available resources for the utilization as a substitute for sponge iron, which is imported. In this study it is attempted to optimize composition and sintering temperature of iron ore pellets which are having the best properties, using the Dela iron ore, lime and coconut shell charcoal. Different combinations of pellets are prepared by changing Coconut shell charcoal percentage and sintering under different temperatures while lime content is fixed. The pellets which are having optimum properties such as Compressive strength and Porosity are selected and it has been observed the most suitable combination for reducibility.
