  • Kinetics of Coal Flotation911 Metallurgist

     · The reason for proposing this distribution is that in coal flotation most of the material in the cell is the flotable component. In order to evaluate the suitability of the various models on the flotation time/recovery profiles of the three coals the results for flotation of the 100 and 200-mesh wet ground coals were used.

  • Evaporative Drying of Low-Rank Coal IntechOpen

     · Low-rank coals including the brown and the subbituminous coals are commonly known to contain high moisture content (up to 65 wet basis) which limits their utilization around the world in spite of their low cost. Today the most of the drying technologies are based on the evaporation of the water from the moist product. In this chapter the most effective parameters on the evaporative coal
