Comparative Studies of Coal Quality Obtained from Ankpa, and Chikila, Nigeria towards Metallurgical Applications

This study presents a comparative analysis of coal quality obtained from two different coal deposits in Nigeria: Ankpa, Mamu formation, Anambra Basin in Kogi State, and Chikila, Guyuk Local Government, Adamawa State. The primary goal was to evaluate the fuel quality and elemental composition of coal from these regions to determine their suitability for various industrial applications. Samples from both locations underwent X-ray fluorescence (XRF) for chemical composition analysis and proximate analysis to assess moisture content, volatile matter, ash content, and fixed carbon levels. The findings revealed significant differences in the chemical and physical properties of the coal from the two locations. Ankpa coal exhibited higher fixed carbon (49.5%) and calorific value (5600 kcal/kg), making it more suitable for industrial applications such as power generation and metallurgical processes. In contrast, Chikila coal had lower fixed carbon (37%) and calorific value (5400 kcal/kg), indicating a lower energy potential. The study concludes that Ankpa coal is more appropriate for energy generation, while Chikila coal may have specialized uses due to its mineral composition. The results contribute to better decision-making regarding coal utilization in Nigeria’s energy and industrial sectors.
