Studies were carried out on the proximate and elemental contents of coal deposits in three Nigerian States (Enugu, Benue and Delta) employing standard laboratory procedures and instrumentation. The fixed carbon and ash contents of Benue and Enugu coal samples deposits were found higher than Delta coal deposits. Heavy metals like arsenic, lead and cadmium were present at higher concentrations in Delta coal sample deposits than in the other coal sample deposits studied. Trace mineral contents of Enugu coal deposits were found to be higher than others implying that it is of higher economic value.
