Geochemical aspects of Amynteon lignites, Northern Greece

Several lignite samples were collected from Amynteon lignite mine, Northern Greece. Chemical analysis for major and trace elements was conducted with the help of X-ray fluorescence and inductively coupled plasma-atomic emission spectroscopy methods. Trace element concentrations of Amynteon lignites have equal or slightly higher values when compared to other worldwide coals. Boron content implies that the lowest lignite beds raised in a middle brackish environment, while the upper lignite beds had a fresh water environment of deposition. Correlation and cluster analysis revealed an inorganic affinity for the elements Al, Si, Ti, Fe, Mg, K, Na, Ni, Cu, Ba, Mo and Sr, while Ca, Cr, Mn, Zn, P, Cd, Sb, Pb, S, B, Co and W, and only F showed an organic affinity. The calculated slagging and fouling indices indicate medium to high slagging and high to severe fouling propensity.
