Adsorption properties of Ca2+ on Na-kaolinite and its effect on flocculation using polyacrylamides

Influence of hydrated lime on the surface properties and interaction of kaolinite particles

“…The adsorption of the first hydrolysis product of Ca (CaOH + ), which starts to form at pH ≥ 10 (Mpofu et al, 2003(Mpofu et al, , 2005, is reported to be the main cause for negative to positive charge reversal. Similar hydrolysable metal ion-mineral particle zeta potential behavior has been reported in other studies (James and Healy, 1972;Atesok et al, 1988;Mpofu et al, 2003Mpofu et al, , 2005.…”

Role of hydrolyzable metal cations in starch–kaolinite interactions

“…For example, Atesok et al (1988) reported that calcium has only a weak effect on kaolinite aggregation, in contrast to the strong aggregation of quartz induced by calcium. Since hydrolysable metal cations are commonly found in iron ore flotation pulp, it is imperative to systematically study the role of hydrolysable metal cations in starch-kaolinite interactions under iron ore flotation and selective flocculation conditions.…”

Temperature influence of nonionic polyethylene oxide and anionic polyacrylamide on flocculation and dewatering behavior of kaolinite dispersions

“…However, this good settling behavior is invariably accompanied by space-filling flocs and thickener underflow tails of characteristically low solid loadings (e.g., 20-30 wt%) [1][2][3]. and hydrolyzable metal ions, particle surface area, size, zeta potential, and solid concentration [15][16][17][18][19][20][21].…”
