Recent research led by Yusuf Jimoh from the Department of Geology and Mineral Science at Kwara State University has shed light on the geochemistry and mineralogy of Maastrichtian coals from Nigeria’s Anambra and Gongola basins. This study, published in the Journal of Economic Geology, is particularly timely as Nigeria seeks to diversify its energy sources amid ongoing power generation challenges.
The research focused on coals sourced from Ankpa in Kogi State and Maiganga in Gombe State. By conducting a series of analyses, including proximate and ultimate assessments, the study aimed to evaluate the quality and resource potential of these coals, which are crucial for energy production. The findings revealed that the coals from Ankpa have an average moisture content of 5.54%, with significant amounts of volatile matter making them suitable for combustion. In contrast, Maiganga coals exhibited a higher moisture content of 10.68%, but still maintained characteristics that favor electric power generation.
Jimoh noted that “the average values of moisture content, ash, volatile matter, and fixed carbon indicate high volatile sub-bituminous non-coking coals that are optimum for combustion and electric power generation.” This suggests that these coals could play a vital role in Nigeria’s energy landscape, especially as the country looks to coal as a more stable and accessible resource.
The study also highlighted the mineral composition of the coals, with Ankpa coals showing a higher presence of authigenic minerals like quartz, pyrite, and calcite, while Maiganga coals contained more detrital minerals such as kaolinite. This mineralogical insight is essential for industries involved in coal processing and utilization, as it can influence the efficiency and environmental impact of coal combustion.
Furthermore, the research assessed the agglomeration characteristics of the coals, which are crucial for their handling and processing in industrial applications. The results indicated a range of agglomeration strengths, with Maiganga coals rated as strong, making them particularly promising for commercial use.
As Nigeria continues to grapple with energy supply issues, the findings from this research present significant commercial opportunities for sectors involved in coal mining, energy production, and related industries. By leveraging the insights provided by Jimoh and his team, stakeholders can better understand the potential of these coal resources, paving the way for enhanced energy security and economic growth.
This research underscores the importance of local resources in addressing Nigeria’s energy needs and highlights the role of scientific inquiry in uncovering the potential of the country’s natural assets. The findings contribute valuable knowledge to the growing discourse on sustainable energy solutions in Nigeria, as the nation seeks to harness its coal reserves effectively.
