Fly ash, generated during the combustion of coal for energy production, is an industrial by-product which is recognized as an environmental pollutant. Because of the environmental problems presented by the fly ash, considerable research has been undertaken on the subject worldwide. An industrial fly ash sample was separated by different processes, which were triboelectrostatic separation, ultrasonic column agglomeration, and column flotation, froth flotation, air classifier, magnetic separation and gravity separation. In the present study the percentage of unburnt carbon present in fly ash is calculated by froth flotation process. The forth flotation process is a good technique to separate unburnt carbon contents in fly ash. This unburnt carbon will create the pollution in environment also decrease the efficiency of thermal plant. So must be kept within the permissible limits.
