Title : The determination of agbaja iron ore characterization and swelling analysis for engineering applications
Abstract:
The determination of Agbaja iron ore characterization and swelling analysis for engineering application was performed. The ore used for this research work was sourced from the Agbaja Plateau in Kogi State. The microstructure and the morphological examinations were carried out with an inverted metallurgical microscope and SEM/ XDS techniques. An inverted metallic microscope was used to analyze the microstructures of the ores. Thermogravimetry, Differential Thermal Analyzer, X-Ray Fluorescence, and X-Ray Diffraction were used to analyze the ore's chemical composition and structural composition. The iron ore was heated in the muffle furnace to calculate the swelling percentage. The iron ore lumps were crushed into pieces ranging in size from +10 to 15 mm, which were then held inside stainless steel containers with a diameter of 60.75 mm x 59.40 mm inside and mouths that were tightly sealed by an airtight cover having an outlet for escape gas. Some numbers of samples were used for the experiments. The samples were subjected to a temperature of 30mins to 130 mins with an interval range of 20mins while the temperature at which the ores were heated in the muffle furnace was to various temperatures from 800oC to 1000oC with an interval of 40oC. The samples were weighed with a digital weighing balance where their initial and final weighs were determined to ascertain the level of swelling. A value of 3.12% was obtained at 800oC at 30mins as the lowest point, while the highest value of 3.67% was obtained at 1000oC. A value of 3.24% was obtained at 800oC at 50mins as the lowest point, while the highest value of 4.44% was obtained at 1000oC. A value of 3.55% was obtained at 800oC at 70mins as the lowest point, while the highest value of 4.55% was obtained at 1000oC. A value of 3.54% was obtained at 800oC at 90mins as the lowest point, while the highest value of 5.10% was obtained at 1000oC. A value of 3.62% was obtained at 800oC at 110mins as the lowest point, while the highest value of 5.27% was obtained at 1000oC and subsequently, a value of 3.93% was obtained at 800oC for 130mins as the lowest point, while the highest values of 5.52% were obtained at 1000oC
