Modeling of Free and Hindered Settling Conditions for Fine Coal Beneficiation Through a Falcon Concentrator

摘要: In this study, the free and hindered settling conditions for coal-shale-clay separation through a Falcon concentrator were determined experimentally using response surface methodology. The model parameters consisted of efficiency ash content concentrate tailings. Based on with highest response, dominated at centrifugal forces below 100 g solid concentrations up to 30%–35%, especially coarser particle sizes 300 µm. These results revealed that, effective fine coal beneficiation concentrator, concentration should be maintained higher than 30%–35% (with maximum 45%–50%) create because under these is achieved based specific gravity. best obtained 50%. This finding was interesting separations enhanced gravity separators similar pe...
