Critical Appraisal of Coal Gangue and Activated Coal Gangue for Sustainable Engineering Applications

open access: yesApplied Sciences
Coal gangue, a primary solid waste by-product of coal mining and processing, constitutes approximately 10–15% of total coal output. Its accumulation poses substantial environmental challenges, including land occupation, spontaneous combustion, acid mine drainage, and heavy metal leaching. Despite its high silica and alumina content (typically exceeding
