The flotation characteristics of Shenfu coal macerals was researched.Taking flotation recovery and enrichment of macerals as the evaluation objects,the influence of the agent dosage,pulp concentration,impeller speed and aeration rate on the separating effect was investigated.And the optimum process conditions of flotation were confirmed.The results show that the agent dosage,pulp concentration,impeller speed and aeration rate have a significant impact on flotation recovery and enrichment of macerals.The float recovery was 73.28％ and enrichment ratio of vitrinite was 83.89％ when CTAB dosage of 1.0 kg/t,pulp concentration of 100 g/L,impeller speed of 1 700 r/min and aeration rate of 0.25 m3/(m2·min) were used.The tailings yield was 60.30％ and enrichment ratio of inertinite was 61.44％ when CTAB dosage of 0.5 kg/t,pulp concentration of 100 g/L,impeller speed of 1 700 r/min and aeration rate of 0.20 m3/(m2·min) were used.
