The regions of dispersion, coagulation precipitation, coagulation flotation, and redispersion were determined for aqueous bentonite-cationic surfactant and bentonite-cationic surfactant-polyacrylamide(PAA) systems. The region of coagulation flotation was markedly extended by the addition of PAA to both the lower and higher concentration regions of the cationic surfactant, hexadecyldimethylbenzylammonium chloride(HDBAC), and to the lower concentration region of bentonite. The phenomenon of coagulation flotation was investigated in detail and was applied to the removal of Co<SUP>2+</SUP> ions and nuclear fission products, <SUP>144</SUP>Ce and <SUP>155</SUP>Eu, from an aqueous solution. The composition of the reagents for the maximum efficiency of bentonite flotation corresponded to that of the maximum efficiency of Co<SUP>2+</SUP>-ion flotation. The effect of the pH on the flotation efficiency was studied in particular. The maximum flotation efficiency of 96% was obtained at pH 11 for Co<SUP>2+</SUP> ions, 86% at pH 9.7 for <SUP>144</SUP>Ce, and 93% at pH 10.5 for <SUP>155</SUP>Eu. These radioactive elements were almost completely adsorbed on the surface of bentonite particles and were floated with them in the pH region of the maximum flotation efficiency. It was confirmed that Co<SUP>2+</SUP> ions could be floated also from an extremely low concentration (10<SUP>−9</SUP> mol/l) of Co<SUP>2+</SUP> ions with nearly the same efficiency of flotation and with the additives in the same condition. Co<SUP>2+</SUP> ions could also be effectively removed by using the step-by-step flotation, showing as high a flotation efficiency as 99.8%.
