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 carbonaceous material and firing temperature, affected the quality of pellets produced. Analysis and tests showed that the firing temperature and the constituent minerals had a significant influence such properties as compression strength, % apparent porosity, bulk density and % water absorption. Also, the pellets which were subjected to a higher firing temperature revealed improved compressive strength, % water absorption, % apparent porosity and bulk density than pellets fired at a lower temperature, this suggesting a more developed solid state reaction between the raw materials at high firing temperatures.
