     the effects of reagents distribution on the recovery of combustible matter and ash content of zirab coal have been studied by using flotation kinetics. rather than the practice of adding the reagents only at the conditioner (i. e. 100-0%), various combinations of stage addition were examined. it was found that a 70-30 % addition regimen could increase the coal recovery by 1.21% ,due to the recovery of coarser particles. these results have been verified with flotation kinetics, in order to accurately determine the rougher flotation efficiency for various flotation conditions.
