Abstract
It is shown that the stability of the water and salt dispersion of kaolin decreases with the introduction of a cationic polyelectrolyte and its mixtures with a surfactant. The flocculating ability of the cationic polyelectrolyte decreases with increasing content of ionic groups. An increase in flocculation in a salt medium was established with the introduction of the mixture of polyelectrolyte with an anionic surfactant, as well as with the sequential addition of components to the kaolin dispersion.
