TRACE ELEMENTS ANALYSIS OF OKABA COAL AND OTHER ENVIRONMENTAL IMPLICATION

Abstract

Trace elements analytical studies were carried out on coal samples from Okaba coal deposits in the Lower Benue Trough of Nigeria to ascertain their constitutional levels and consequent environmental impact. Chemical analyses of the coal samples indicated that they contain on average basis 2.77% Fe, 0.06% Mn, 13ppm Cd and 0.013ppm Ni. Copper was not detected in any of the samples. The trace elements show concentrations generally lower than the generally anticipated concentrations in coals. This implies that the mining processing and utilization of Okaba coal will have only minimal negative environmental and health impacts on account of its negligible trace elements contents.
