The aim of this study is geochemical analysis of flying ash generated by the combustion of lignite in the Kostolac A and B thermal power plants. The fractionation procedure of fly ash samples was done firstly, and then stereomicroscopy, FTIR, SEM / EDS and ICP-OES analyzes. The contents of heavy metals V, Cr, Mn, Co, Ni, Cu, Zn, Cd and Pb were determined. The results showed that the concentrations of the tested heavy metals are within the limits that are not harmful to the human health. However, the mineralogical analysis of the mentioned ash indicates that the present glass and other high-temperature mineralogical components can cause respiratory problems and disfunction of other organs of the inhabitants of Kostolac and the immediate surrounding. The tested fly ash, also, can be used as a material in various fields of industry (e.g. construction). Key words: lignite, fly ash, Kostolac, heavy metals.
