TL;DR: In this article, the viscous flow behavior of a colloidal sol can be described in terms of the various contributions to the energy dissipation during flow, and a satisfactory description of the known features of the basic shear diagram can be obtained by attributing most of the dissipation to two processes: (i) viscous flows of the suspension medium around the flocs, which are the basic flow units, and (ii) the energy involved in stretching the flos in order to break floc doublets apart so that the amount of structure in the system is

TL;DR: In this article, the flow properties of electrically charged, but unstable, colloidal sols are investigated in the light of three possible models, i.e., hard (nondeformable) floc, elastic floc and hard (non-nondefinite) particle model, and they are shown to provide a consistent physical interpretation of both the linear region of the flow curve and the Bingham yield value.

TL;DR: In this paper, the relationship between the experimental flow parameters and the colloidal parameters (volume fraction, particle size, and interactive forces) is examined and ten such relationships can be used to test the validity of possible models of the flow of coagulated suspensions.

TL;DR: In this paper, the authors investigated the effect of the presence of coal particles in MgCl 2, NaCl, and NaClO 3 solutions in the absence and presence of a strong frother, i.e., Dowfroth 250.

TL;DR: In this paper, the effect of floc structure on coal tailings dewatering and the impact of shear-induced modification of the floc network structure on additional sediment consolidation and densification have been examined.
