This study focuses on the determination and concentration of twelve elements (Na, K, Ca, Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn and Cd)
occurring in sub-bituminous Assam coals and their geochemical association. Distribution of these elements between organic and mineral
matters was studied. Comparison of the results of three coals has shown that three elements (Mg, Ca and Mn) are significantly organic bound,
while five elements (Fe, Co, Ni, Cu and Zn) are significantly mineral bound; Cd is 50% bound to either organic or mineral matter. FTIR and
XRD studies reveal qualitative information about the bonding pattern and nature of components of the mineral matters. The results obtained
in this study have considerable geochemical and technological interest
