Abstract: The effect of addition of the sodium carbonate and soda water-glass and their concentration for different kaolin slurry was investigated. The significant decreasing of the apparent viscosity and the yield stress was observed due to the addition of the both peptising agents. The viscosity difference between coagulated and peptised slurries can achieve values of several orders of magnitudes depending on peptising agent concentrations. The modification of physico-chemical environment of the transported slurry can be used also for another fine-grained dense hydro-mixture, e.g. for different mine tailings or for bauxite residue.
