In this study, the ash was sulfurized in an autoclave before flotation. The sulfurization process was conducted at different amounts of H2S and H2O steam. The flotation process was continued with the obtained samples. By flotation of the sample obtained from optimum sulfurization conditions, the concentrates containing all the uranium, molybdenum, vanadium, nickel and titanium was obtained. It was established that the above mentioned elements were enriched 12 times more than the original ash at the concentrate phase. The original ash was tried to enriched by flotation. However, the results obtained from this study was not encouraging. Therefore, ash was sulfurized in autoclave before flotation. In the flotation studies K-isobutylxanthate and Kamylxanthate were used as the collectors and the Aeroflat 65 was used as the frother.
