摘　　要：为了解双子表面活性剂对煤泥浮选效果的影响,在对不同煤样煤质分析基础上,对双子表面活性剂作用下的不同煤样、不同浮选药剂及浮选速度进行试验研究。试验结果表明:双子表面活性剂对不同煤种、不同浮选药剂适用性强,可显著改善浮选效果,降低浮选药剂用量,提高精煤产率。在浮选过程中选择合适的双子表面活性剂有利于改善浮选效果,从而为选煤厂带来较好的技术经济效益。In order to find the influence of gemini surfactant on the result of slime floatation, based on the analysis of different coal samples, the experiments of different coal samples, different floatation rea- gents and floatation rate under the effect of gemini surfactant are studied. The experiment results show that the gemini surfactant is adaptive to different kinds of coal and different kinds of floatation reagents and can significantly improve the floatation effect, reduce the consumption of floatation reagent and in- crease the yield of clean coal. During the flotation process, select the suitable gemini surfactant help im- prove flotation effect, thus bring better technical feedback and economic benefit.
