Özet

Large amounts of fine coals are produced in the word due to increased mechanization in coal mining and performance inability of processing of coals. In coal cleaning plants, these coal fines are reported to tailings causing an environmental pollution and loss of valuable energy source. Therefore, recovery of fine coals from the tailings has significant importance for human health and saving of energy sources. Gravity techniques cannot be applied for cleaning and recovery of coal fines. Although flotation is considered to treat fine coals, satisfied quality of coal cannot be obtained. Oil agglomeration is a promising a candidate for deashing and desulphurization of fine coal and recovery of fine coal from the tailings. In this study, fine coal recovery from the tailings of a Turkish coal washery by oil agglomeration method was investigated. Effect of the particle size on the performance of the process was investigated.
