| Abstract: | Aimed at solving the problem that high content of unburned carbon in fly ash is unfavourable to the comprehensive utilization on a large scale. The flow path with full flotation against the recovery of unburned carbon in fly ash is tested. The main factors affecting the result of flotation of unburned carbon in fly ash are also discussed. The appropriate process conditons are determined. The results show that the flow path with full flotation can greatly improve the recovery of unburned carbon in fly ash and efficiently decrease the carbon content in fly ash. |

| Keywords: | fly ash flotation unburned carbon recovery carbon content decrease |
