In coal mining, large amounts of fine coals are produced during excavation, transportation and processing. If their qualities are low, these fine coals should be cleaned and evaluated as energy source. In the present study, cleaning possibility of the fine coal with oxidized - brittle structure by selective attrition in a laboratory scale pin-type vertical stirred mill without grinding media and the subsequent screening was investigated. The stirring speed, attrition time and screen size were examined as variables. It was determined that 1.70 - 22.45% of ash could be rejected from the coal with combustible matter recoveries of 24.92 - 98.99%
