Froth flotation is a highly versatile method for separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The present study reported a new approach towards optimization of coal flotation process through combustible recovery. The experimental work was evaluated in two stages. In the first stage the ash content percentage of the froth was calculated using various dosage of collector and Frother. Methyl Isobutyl Carbinol is used as Frother and Kerosene is used as Collector for this experiment and finally the optimum dosage ratio of “Collector – Frother” were calculated to find the minimum ash content. In the second stage coal recovery values were calculated by floating various slurry concentration for 2,3,5,8 and 10 min of floatation times. Later Coal recovery (%), Ash recovery (%), Ash rejection (%) and Separation Efficiency values were also evaluated. Final concentrate was obtained with 93.08% of combustible recovery and 20.64% of ash content at optimum conditions after 10 minutes of flotation time.
