VALUABLE PRODUCTS FROM FLY ASH A REVIEW Open Access

IntroductionApplicationsRecovery of Silica and AluminaConclusionReferencesGeneral Coal is the major source of energy in India and it accounts about 70% of the power production (Kolay et al. 2001; Mishra et al. 2004). Combustion of coal in thermal power plants produces fly ash. There are different types of coal namely anthracite, bituminous, sub bituminous and lignite. Classification of coal is based on the content of volatile matter and carbon. Coal which has less volatiles and high carbon is of superior quality. High rank coals are harder, stronger wit
