摘　　要：针对细粒煤泥的浮选特性,将选煤用煤油捕收剂乳化处理后使用,结果表明:乳化煤油具有捕收能力强、选择性高的特点,可以显著提高细粒煤的浮选效果,降低捕收剂消耗,具有显著的经济效益及社会效益,并从理论上对乳化剂的作用机理进行了阐述。In view of the characteristics of fine coal flotation , kerosene which is used as collector in coal separation was emulsified. The results show that the emulsified kerosene with a strong collector ability and high selectivity can significantly improve the flotation performance of fine coal and reduce the collector consumption , also has remarkable economic and social benefits. The theoretical action mechanism of the emulsifying reagent is described.
