Comminution as an energy-intensive operation must be economically feasible for a meaningful trade... more Comminution as an energy-intensive operation must be economically feasible for a meaningful trade in mineral resource. Therefore, the energy required to grind one tonne of an ore from a given feed particle size to a specified product particle size is a critical material property. This study evaluates the resistance of Ningi Graphite Ore to grinding using coal as a reference ore. Ore samples were extracted, homogenized, and transported to the laboratory. Crushing and grinding were done under standardized conditions using pulverizer and ball mill respectively. Fractional sieving was carried out using automatic sieve shaker. From Gates-Gaudin-Schuhmann Expression, particle size analyses of the mill feeds and products indicate the mesh grinds to be 415µm and 168µm for the test sample, and 2659µm and 178µm for the reference ore sample. The study shows that approximately 39.77Kwh of energy is required to reduce one tonne of Ningi Graphite ore from 80% passing of 415.43µm size to 80% passing of 167.83µm.
