Rare-Earth Elements Extraction from Low-Alkali Desilicated Coal Fly Ash by (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub> + H<sub>2</sub>SO<sub>4</sub>

Coal fly ash (CFA) obtained from pulverized coal furnaces is a highly refractory waste that can be used for alumina and rare-earth elements (REEs) extraction. The REEs in this type of CFA are associated with a mullite and amorphous glassy mass that forms a core-shell structure. In this research, it...
