Although all developments in the energy industry, coal holds still its vital place and seems to will have a major role in future. That is why the direct utilisation of coal becomes impracticable even impossible in those days. Thus, the aim of this review is that all aspects of dry coal cleaning methods are overviewed, analysed and evaluated, including the applicability to the industry in the face of wet methods. The density-based methods have potential than other dry coal cleaning methods and had made great development within the coal preparation industry. The Ep values of air jigs or air tables are between 0.13 and 0.26 g/cm3, but fluidised bed separation method has between 0.03 and 0.07 g/cm3 and it provides to rivalry with wet methods and is a serious alternative for coal preparation.
