摘要

This article examines the application of dry beneficiation technology to the separation of coal and mineral matter in a novel air-fluidized bed. The Reflux Classifier (RC) is an innovative design that incorporates an inclined zone above a conventional fluidized bed to achieve increased segregation rates and a higher throughput than separators with an equivalent footprint. In this study, the effectiveness of magnetite and sand as dense media for the separation of coal in an air-fluidized RC was evaluated. The effect of vibration on the separations obtained using both these media was also examined. The coal separation results are reported and compared with coal washability data.
