The Research On Influencing Rules Of Several Kinds Of Water-Soluble And High-Molecular Compound On Flotation And Filtering Of Coal

Through the applications of four kinds of water-soluble and high-molecular compound ,such as PEO,PAM, Polyacrylic acid-natrium and Chttosan, on flotation and filtering of fine coal ,we studied their influences on flotation and filtering . Then we choose a kind of PAM ,which is applied on industrial experiments, and we also test its effects on mining processing industry.Taking lean coal from Ximing , coke from Tunlan and fat coals from Zhenchengdi as the experimental objects we want to conclude the influencing rules of the agendas mentioned before by the study of yield, ash filtering speed and moisture of the cake . And we analysed the mechanism of flocculation and filter aid by ways of dynamics analysis and electron microscope.During the research on flotation of the coal from Ximing we observed that high-molecular PEO(4# to 6#) have great effects that it can increase the yield and ash . In PAM categories , the agentias of standard whose molecular...
