    Recovery of Trace and Heavy Metals from Coal Combustion

    The dry disposal method creates air pollution initially, and the wet disposal method creates water pollution as a result of the presence of trace and heavy metals. These leached heavy metals from fly ash may become more hazardous when they form toxic compounds such as arsenic sulfite (As 2 S 3 ) and lead nitrate (N 2 O 6 Pb).
