Abstract:
Industrial minerals such as kaolin, are too fine feature sizes, the presence of these colloidal systems is related in some way to strong distortions of the rheological behavior and the possibility of bringing these minerals mining and metallurgical processes.Colloidal systems in the mineral kaolinite, from La Unión, Antioquia, Colombia, were analyzed by the following physico-chemical techniques: Potential Z, DTP laser, tensiometry, high-resolution optical microscopy and rheometry. The object of these trials was to determine the stability of such suspensions as a function of surface activity under the concepts of colloidal and from the thermomechanic. The analysis results show that the excess concentration of colloidal minerals and nanoclay dispersions of kaolinite, generate strong effects of mechanical energy dissipation, but when concentrations are controlled under any scheme of concentration, the energy dissipation mechanics decrease if you look at the problem from a perspective of the DLVO theory.
