Research on the Selective Flocculant of Soluble Starch and Acrylamide Graft Copolymer for Fine Hematite Particle

This paper, a comprehensive analysis of selective flocculation am fine hematite selected based on the combination of soluble starch and the characteristics of acrylamide was prepared soluble starch - grafting of acrylamide polymer flocculant. We can see through selective testing, the preparation of starch - acrylamide graft polymer of pure quartz and pure hematite were produced on the surface adsorption, through the measured absorbance and then converted to the concentration of ways we can see remnants of the graft material in the quartz very small amount of surface adsorption, while in hematite adsorption volumes. By hematite flocculation test we can see, with flocculants prepared by flocculation, its ability to better than selective flocculation modified maize starch and polyacrylamide.
