原始语种摘要: Abstract(#br)Beneficiation of fine (−1.0mm) coal in air table was studied both from theoretical and experimental angles. Experiments were performed according to Response Surface Method with high ash (43%) coal fines using air table. The features of separation were established and favorable operating regimes identified for the targeted product. About 10% (absolute) reduction in the ash level was achieved in single stage operation with a reasonably high product yield. Separation in air table was described by a set of mathematical equations. It was established that the vertical stratification and horizontal segregation are the two phenomena responsible for separation. Both these phenomena are described mathematically from a fundamental standpoint using force balance...
