Resumen

Ultrafine coal (nominal 150 × 44 μm) cleaning using a pilot-scale, centrifugal fluidized bed separator was investigated. The effects of the operating parameter values were evaluated and optimized to maximize mass recovery at a given product grade. Significant ash reductions were achieved from the cleaning of two coal sources having different cleaning characteristics. The concentrator provided a range of separation densities between 1.46RD to 2.18 RD with probable error (E_P) values of around 0.25. Rougher-scavenger circuit simulations indicate that the process efficiencies can be improved significantly while achieving low density separations. E _P values ranging from 0.17 to 0.20 were realized, while the organic efficiency increased by 20 absolute percentage points.
