Processing of Coal Fly Ash for the Extraction of Alumina

Processing of Coal Fly Ash for the Extraction of Alumina

May 08, 2020 Abstract Coal fly ash is a lightweight incombustible particulate generated during coal combustion. Alumina content in the fly ash is present in the mullite phase, and its high stability calls for alternative processing for conversion to reactive phase before leaching. Mechanical activation with sodium hydroxide was found unsatisfactory for the breakdown of mullite structure, whereas the ...
