Effect of flocculants and electrolytes on the stability of kaolin hydrosuspension
The paper considers the effect of electrolyte on the stability of kaolin hydrosuspension in the presence of cationic flocculants with different charge density. The significant acceleration of bentonite particle sedimentation by the presence of electrolytes NaCl and CaCl2 was found out. The increase of cation valency and electrolyte concentration leads to increase of this tendency. In the absence of electrolyte the flocculating action of cationic flocculants FO41159H, Z89 and FO4800SH is intensified with charge density increase. It is caused by formation of large floccules. The mixture of electrolyte and flocculant has more intensive flocculating action than the individual components. The flocculating action depends on the electrolyte/flocculant ratio and way of introduction of components into hydrosuspension.
