This paper presents the results of flotation studies carried out on a non-coking coal sample for reduction of ash. The effects of various process parameters on the floatability of coal have been studied. The effects of ultrasonication and emulsification of the oily reagents have been studied on the flotation behaviour of coal. The data have been analysed kinetically using first order model. It was found that ultrasonication of the oily reagents adds to the selectivity of separation while emulsification improves the recovery of carbon values. The improvement in the flotation performance was attributed to the fine dispersion and selective adsorption of the oily reagents caused due to ultrasonication and emuls-ification.
