Coal and lignite, essential to worldwide energy production, cause emissions and ash management issues. Coal/lignite beneficiation is promising for economic and environmental advantages. This literature review and empirical study examines its effects on emissions reduction, pollution management, and ash handling efficiency. The sustainable solution research assesses emissions reduction methods and reveals hidden benefits like ecological benefits. The findings support coal/lignite beneficiation in energy production and inform policymakers, energy producers, and environmental stakeholders. This study discusses contemporary beneficiation technologies, including RAMDARS, and suggests a promising energy future. Combining detailed research and a case study shows the industry's revolutionary potential. A bright perspective beyond technological development emphasizes the sector's preparedness to contribute significantly to a sustainable energy future through continual innovation, cooperation, and RAMDARS integration.
