New reagent systems for the flotation of kaolinite

Dispersion stability of a ceramic glaze achieved through ionic surfactant adsorption

“…The adsorption of both CPC and SDBS on feldspar and kaolinite has been studied by Köster et al [18]. The surfactant concentration in equilibrium with the adsorption maximum of CPC is in the region of the CMC.…”

“…On a heterogeneous charged surface such as kaolinite, the first stage of anionic surfactant adsorption is thought to result in a monolayer coverage on the positively charged edges through electrostatic adsorption of the anionic headgroups [18,24]. Further addition of surfactant results in small surface aggregates formed via hydrophobic interactions.…”

“…In previous studies, the effect of pH, ionic strength, and surfactant concentration on the adsorption of surfactants has only been studied on the single mineral ceramic glaze components, namely, silica [8][9][10][11][12][13][14][15], quartz [16,17], feldspar [18], kaolinite [19][20][21][22][23][24][25][26][27], and limestone [28][29][30].…”

Flotation of kaolinite from tailings of kaolin-washing plants by cationic collectors

“…The results of these studies showed that kaolinite flotation by cationic collectors was better under acidic conditions than in alkaline media [7][8][9][10][11][12][13]. Yuehua et al (2004) tried to increase kaolinite recovery in alkaline medium by using a macromolecule as a flocculant.…”

“…Both minerals are negatively charged in a wide range of pH, and therefore they can be floated by amine collectors in acidic and alkaline medium [6][7][8].…”
