Salt coagulation or flocculation? In situ zeta potential study on ion correlation and slime coating with the presence of clay: A case of coal slurry aggregation.
31
TL;DR: The result suggests that aggregation of coal slurry by calcium ions in the presence of clay minerals belongs to fluctuations, and the ion correlation and slime coating could be detected by ESA with a decrease in zeta potential under high calcium ion concentration conditions.

A study on the mechanism of calcium ion in promoting the sedimentation of illite particles
TL;DR: In this article, the influence of Ca2+ on the sedimentation effect of illite was investigated under different Ca2 + concentrations, and the results showed that with the increase of Ca 2+ concentration, the equilibrium adsorption capacity of the illite increased and achieved at 60min.

Surface charge heterogeneity of kaolinite in aqueous suspension in comparison with montmorillonite
Etelka Tombácz,Márta Szekeres +1 more
TL;DR: Tombacz et al. as mentioned in this paper performed a similar study on 1:1 type kaolinite obtained from Zettlitz kaolin and showed that the pH-dependent charge formation was similar, positive charges in the protonation reaction of (Si-O) Al-OH sites formed only at pHs below ∼ 6-6.5, considered as the point of zero net proton charge (PZNPC) of kaolin particles.
