The effect of dolomitic lime and the firing temperature on the properties of pellets produced from dela iron ore

Abstract

Iron ores and lime are two of the available raw materials in Sri Lanka for iron making. However, proven reserves of I iron ore deposits in Sri Lanka have not been scientifically estimated as yet. There is no indication of the occurrence I 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 the dolomitic I lime content and firing temperature in producing high quality iron ore pellets.
