This paper deals with the flotation studies carried out on a non-coking coal sample for reduction of ash below 10%. The effects of various process paramaters on the floatability of coal have been studied. The effects of ultrasonication and emulsification of the oily reagents have been studied on the floatation behaviour of coal. The data have been analysed kinetically using first order model. It was found that ultrasonication of the oily rea-gents adds to the selectivity of seperation while emulsi-fication improves the recovery of carbon values. The improvement in the floatation peformance was attributed to the fine dispersion and selective adsorption of the oily reagents caused due to ultrasonication and emulsification.
