  • FINE COAL DEWATERING

    FINE COAL DEWATERING Gul Bahar Basim (ABSTRACT) Fine coal constitutes a relatively small portion of a product stream in a coal cleaning plant. However, its processing cost is approximately three times higher than the cost of processing coarse coal. Therefore, many coal companies chose to discard the fines to refuse ponds, causing a loss of profit and creating environmental concerns. This ...

     · Flocculation followed by filtration is a new concept for the dewatering of coal plant tailings. This study clearly indies that the proper use of flocculant in filtration was very important to achieve efficient filtration performance. At the optimum dosage, the flocculant improved the dewatering process. For example, very large flocs gave rapid sedimentation but very poor filtration rate and ...
