Title: Influence of PAM on oil emulsified and slurry floatation
Abstract: In order to study the impact of PAM on the kerosene emulsion stability and the coal slurry flotation effects,this paper discusses the kerosene emulsification experiment carried out,choosing different volume contents in a mechanical rabble way and the unit flotation contrast experiment carried out,using kerosene,kerosene + PAM,kerosene emulsion and kerosene emulsion +PAM as collector.The result shows that addition of a small amount of PAM aqueous solution to the process of kerosene emulsion preparation leads to an improvement in the speed of kerosene emulsification and an increase in the stability of emulsion;when the oil-water ratio is 1∶1 and the emulsifier is 1%,the emulsion(with the PAM content of 21%) shows the best stability;the increase in volume of PAM,gives gradually improved flotation effect,and the decrease occurs in flotation effect,when the PAM volume is excessive.Compared with the pure kerosene flotation results,the flotation indexes of kerosene+PAM,kerosene emulsion and kerosene emulsion+PAM show improvement to varying degrees and 50% decrease in the kerosene consumption.
