Abstract: Although there are many developments in the energy industry, coal still holds its vital place and seems to have a major role in future. That is why the direct utilisation of coal becomes impractical even impossible in those days. Thus, the aim of this review is for all aspects of dry coal cleaning methods be overviewed, analysed and evaluated, including the applicability to the industry in the face of wet methods. The density-based methods have potential than the other dry coal cleaning methods and have made great development within the coal preparation industry. The Ep values of air jigs or air tables are between 0.13 g/cm³ and 0.26 g/cm³, but fluidised bed separation method are between 0.03 g/cm³ and 0.07 g/cm³. It provides rivalry with wet methods and is a serious alternative for coal preparation. [Received: January 17, 2022; Accepted: July 20, 2022]
