The effects of coal properties and process parameters, such as fluidized bed depth, superficial gas velocity, coal to magnetite feed weight ratio and processing time, on coal cleaning efficiency was experimentally studied in a bubbling fluidized bed separator. The coal cleaning experiments were performed with one various size fractions of Pennsylvania`s bituminous coals, Rushton coal. The performance of the coal cleaning process was measured with the aid of sulfur and ash removal efficiencies. Previous experimental results and those obtained in this study indicated that, when operated in optimum process conditions, coal particle sizes smaller than 240 {micro}m and larger than 143 {micro}m can be cleaned with high performance in the fluidized bed separator. For coal particle sizes smaller than 143 {micro}m, high interparticle cohesive forces caused slugging and channeling inside the bed. As a result of this, relatively poor cleaning performance was recorded for very fine size fraction of Rushton coal.
