Coal washery have produced huge amount of fine tailings called slime. These tailings have also covered huge areas and this makes environmental pollution on site beside contains recoverable fine coals by using conventional and newly developed beneficiation units. In order to recover of fine coals from tailings as well as to rehabilitate of old tailings area, two washery tailings, Tuncbilek and Soma, subjected to this investigation. Spiral and multi gravity separator were used and optimum test results were reported in this paper. Results indicate that two different quality clean coals having low ash content can be obtained. It is possible to reduce ash content of original fine tailings from between 55-68% to 10% and 25% (second quality clean coal) by using gravity separation methods.
