The effect of polyelectrolytes and their mixtures on flocculation of kaolin suspensions
Abstract
The effect of the concentration and charge of the water-soluble polyelectrolytes on the kinetics of aggregation of kaolin particles was studied. It has been shown that the rate of stirring affects formation, size and strength of flocs. The rate of aggregation and the size of the mineral particle forming floccules increase with the increase of reagent concentration and the charge density of the polyelectrolyte. At low concentrations (2.75-3.8 mg/g) of individual polyelectrolytes (FO 4800 SSH, FO 4650 SSH) and content of binary mixtures of polyelectrolytes in the ratio of 1: 9 by mass (0.77 mg/g), the flocculation of mineral suspension increases. Mineral suspension is stabilized at the increase of concentration (>5.5 mg/g).
