ABSTRACT This study presents the beneficiation of coal fines in a Knelson concentrator. With a view to achieving this aim, the bowl speed (250–1250 rpm), fluidization water flow rate (2–4 l/min), solids ratio (10–30%) and feed flow rate (1.5–2.5 l/min) were determined as independent variables. The effects of these variables on the yield of concentrate, the …
