During this process, a by-product known as coal fly ash (CFA) is generated which poses several environmental issues. The common management of the waste involves the disposal of CFA in landfills or the direct disposal to open uncultured lands, thus contaminating water bodies by the leaching of constituent CFA metals and salts that render arable land uncultivable.enCoal fly ashAlkaline fusionAcid precipitationSilica extractHydrothermal treatmentUniversity of Western Cape
