Elemental Composition Of Nigerian Coals

PROXIMATE AND ELEMENTAL ANALYSIS OF SOME NIGERIAN

Coal contains diverse amounts of trace elements in their overall composition (Thomas, 1992).Certain trace elements such as lead, arsenic, cadmium, chromium and mercury if present in high amount could preclude the coal from being used in environmentally sensitive situations (Ward 1984).
