enhanced flocculation and dewatering of clay mineral dispersions

Enhanced flocculation and dewatering of clay mineral dispersions

In order to minimise flocculant aging, all polymer solutions were prepared and used within 3 days. 8 wt.% solid kaolinite or smectite dispersions were prepared by thoroughly mixing a known mass of each clay with a known mass of 10 ? 3 M KNO 3 electrolyte solution at an agitation rate of 250 rpm for 1 h.

efficacy of dispersion of magnesium silicate (talc) in papermaking

Efficacy of dispersion of magnesium silicate (talc) in papermaking

The understanding of the dispersion of papermaking grade fillers is as important as their effect on paper. Magnesium silicate (talc) is one of the major fillers used for papermaking. It is hydrophobic and chemically inert. The dispersion chemistry of talc of different particle sizes was studied with wetting agent (non-ionic triblock copolymer

Polyacrylamide Soil Conditioners: The Impact on Nanostructured Clay Minerals¡¯ Aggregation and Heavy Metals¡¯ Circulation in the Soil

Polyacrylamides (PAMs) are group of water-soluble, synthetic polyelectrolytes derived from acrylamide monomer in polymerization process [ 1, 2, 3 ]. They are substances which dissolve, disperse, or swell in water and thus can modify physical properties of aqueous system due to thickening, gelation, emulsification, or stabilization processes.

Exploring Alternatives to Polyacrylamide: A Comparative Study of Novel Polymers in the Flocculation and Dewatering of Iron Ore Tailings - MDPI

In this study, a 5 wt.% tailing suspension with pH 10 was flocculated with two non-ionic polyacrylamides (PAMs) of different molecular weights (Mw PAM2 > Mw PAM1). Zeta potentials of the supernatant after 24 h flocculation with different dosages of PAM1 and PAM2 were determined to study the effect of these polymers on the surface charge of the suspended particles, and the results are shown in

[PDF] Colloidal and Sedimentation Behavior of Kaolinite Suspension in Presence of Non-Ionic Polyacrylamide (PAM) - Semantic Scholar

Colloidal behavior of kaolinite particles in water was investigated in this manuscript, without and with the addition of a polymer flocculant (non-anionic polyacrylamide (PAM)), using diverse imaging techniques in addition to LUMisizer. The addition of PAM was found to be causing the formation of bridges among particles thus increasing their settling rates to the bottom of the container. To
