Influence of Gemini surfactant on slime floatation

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 reagents 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 increase the yield of clean coal. During the flotation process,select the suitable gemini surfactant help improve flotation effect,thus bring better technical feedback and economic benefit.
