A comparative study of trace elements in Singareni and Talcher coals was carried out using Particle Induced X-ray Emission technique with a 3 MeV proton beam. Concentrations of sixteen elements, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr and Pb were obtained and compared with Clarke’s values to ascertain the enrichment factor for each. Pearson correlation and hierarchical cluster analyses were used to understand the relationship between the inorganic constituents of coal. It is anticipated that this study of trace elements in coals will be useful to protect environment and to regulate the emission of toxic elements during coal combustion and utilization.
