Flocculation of calcite dispersions induced by the adsorption of highly cationic starch
TL;DR: In this paper, the interaction between highly cationic starch and calcite was investigated by determining the adsorption isotherms and the flocculation of the calcite dispersions at different concentrations of starch.

Flocculation of semidilute calcite dispersions induced by anionic sodium polyacrylate-cationic starch complexes
TL;DR: In this article, the performance and mechanisms induced by premixed complexes of cationic starch and anionic sodium polyacrylate (NaPA) on semidilute calcite dispersions were investigated by measuring the particle size and the dynamic mobility.

TL;DR: The flocculation performance of cationic starches on calcite pretreated with anionic sodium polyacrylate was investigated by measuring the mean particle size and the dynamic mobility of the calcite dispersions, and it was demonstrated that the molecular weight and degree of substitution of the starches might be adjusted to control theFlocculation behavior.

Mixtures of cationic starch and anionic polyacrylate used for flocculation of calcium carbonate—influence of electrolytes
TL;DR: In this article, the properties of polyelectrolyte mixtures, used as flocculating agents, were compared to the flocculation behavior of semi-dilute calcium carbonate dispersions.
