Geochemical Characteristics of the Bottom and Pond Fly ash, Neyveli, Cuddalore District, Tamil Nadu, India

Research on finding the trace element in the fly ash material becomes imposing due to environmental effect. Coal fly ash formed from the burning of coal by thermal power plants are huge and it has been a big problem in its disposal. The main aim of this study is geochemistry of fly ash sample from Neyveli thermal power station. Mine-I has a reserve of 365 MT and covers an area of 26.69 sq. km. The tiny mine-IA, which has a reserve of 120 MT, is spread across an area of 11.6 sq. km. The Indian government has approved the expansion of the second Mine’s capacity from 4.7 MT to 10.5 MT. Despite the above listed numerous studies, the behavior of trace elements are still incompletely understood and additional investigations are required. The current study is a thorough examination of trace elements in Neyveli lignite combustion bottom ash and pond ash. In the bottom ash and pond ash, the concentrations of 21 elements (As, Ba, Cr, Ag, Cd, Co, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Rb, Sr, Se, Ti, Zn, Zr, Sb, and Sn) were determined.
