Physicochemical Properties of Fe-Bearing Phases from Commercial Colombian Coal Ash
Santos, Ana Cláudia; Cruz, Cláudia; Font, Eric; French, David; Guedes, Alexandra; Moreira, Karen; Sant'Ovaia, Helena; Vieira, Bruno J. C.High amounts of coal combustion products, such as fly ash and bottom ash, are generated every year; however, only 64% are used, which means that a significant part is landfilled despite containing valuable materials such as ferrospheres, which may be used as catalysts, substituting critical raw materials (e.g., platinoids). In commercial coals, pyrite contents are reduced as a pre-combustion S-emissions control...
