Experimental study on the effect of flocculants on Flotation Process

Take coal slime in Jiexiu coal preparation plant as research object,by using polyacrylamide and St-DMDACC-AM in flotation experiments,and compare the effects of adding the two kinds of flocculants under several appropriate agent systems on the flotation.The results shows that after adding polyacrylamide in flotation experiment,the yield of clean coal increased by 3.06% while the ash content of clean coal little increased,and by adding St-DMDACC-AM,the yield of clean coal increased by 2.69%.
