Abstract

The interaction of a stable clay dispersion from tin tailing slimes from an ex-mining pond with natural rubber latex particles in a mixed colloidal system was investigated as a function of the concentration ofsodium chloride, the cation types, the non-ionic surfactant concentration and the pH. In all cases, the amount of latex adsorbed increased linearly with the latex concentration. The slope of the straight line increased with increasing concentration of NaCl but decreased as the pH of the dispersion was increased. An increase in the slope was taken to indicate an increase in affinity of the latex particles towards theclay surface. The slope was found to increase with an increase in thevalency of the cations used but the reverse effect was found for the non-ionic surfactant concentration. A heterocoagulation mechanism between the two dissimilar types of particles is proposed to explain the observations.
