Abstract
Iron ore pellets which are predominantly being used in the blast furnace and direct reduction processes have undergone improvements in other to improve the aforementioned processes and increase efficiency using different methods. This present work which is of different approach whereby different methods of raw materials selection, composition, presence of binding agents, presence of carbonaceous material and firing temperature, affected the quality of pellets produced. Analysis and tests showed that the addition of binders to the green pellets directly improves the drop number and increased compressive strength of all the samples at higher temperature. The investigations also revealed that starch added samples have high bulk density. In addition, it is observed that the mixing ratio, mixing/coating sequence and pellets composition significantly affects the properties under investigation.
