Melting and Dissolving Fly Ash by NaOH for the Removal of Iron, Calcium, and Other Impurities
A mixture of fly ash and sodium hydroxide was calcined, which converted mullite (3Al2O3·2SiO2), the high-temperature stability phase containing silicon and aluminum oxides, and quartz into activated silica alumina phase, and they were dissolved by concentrated NaOH solution into soluble SiO32− and A...
