A particle size analyzer together with a video camera has been used to investigate the structure of the aggregates during the process of aggregation and breakup of particles in a shear flow induced by means of a Couette-flow system. Three different values for the shear rate have been used (25, 32, a

Small-angle static light scattering has been used to probe the evolution of aggregate size and structure in the shear-induced aggregation of latex particles. The size of aggregates obtained from the particle-sizing instrument (Coulter LS230) was compared with the size of those obtained with another
A modified discrete element method in which the hydrodynamic contribution is taken into account is proposed to simulate the deformation and breakup process of coagulated particles in two-dimensional shear and elongational flows. The simulation was performed for aggregates of various sizes, constitut
## Abstract The biological leaching of sulfide minerals, used for the production of gold, copper, zinc, cobalt, and other metals, is very often carried out in slurry bioreactors, where the shearing between sulfide particles is intensive. In order to be able to improve the efficiency of the bioleach
The spectral time evolution of Methylene Blue (MB) in SWy-1 and in Laponite aqueous clay suspensions are quite different. However, in the presence of added salts the spectral behavior in both clay suspensions becomes similar and approaches that of Laponite. The changes of the spectrum in the Laponit
