Huge non-coking coal deposits need beneficiation with their high ash because of drift origin. A part of coking coal could be replaced with beneficiated non-coking coal in steel industry. The ash levels could be reduced to the desired limits by applying beneficiation techniques including heavy media separation and froth flotation. Collectors coupled with frothrs are usually resorted to in the flotation process. A non-coking coal sample from Raniganj, India analysed 47.33 percent fixed carbon, 35.73 percent volatile matter, 14.94 percent ash and 2.00 percent moisture has been examined in this paper vis-a-vis ash reduction. Various collectors like kerosene oil, light diesel oil and fuel oil along with frothers MIBC, cresylic acid and pine oil were attempted. The role of collectors was examined and efficiency index (EI) of collectors was shown. The EI of kerosene oil (472.51) was higher than the other collectors and the ash was reduced to 11.90 percent with 93.6 percent yield.
