The behavior of cationic and anionic collector mixtures in the feldspar-quartz flotation system has been investigated through conductivity, surface tension, zeta-potential and flotation studies. The results show the formation of mol. complexes between oppositely charged collector ions through charge neutralization. The mol. complexes are found to have a higher surface activity than the individual components. The mole ratio of the mixed composition is found to have a significant effect on flotation. Mole ratio less than unity (anionic/cationic) of collector mixtures increases the flotation recoveries. If the mole fraction of the anionic collector is greater than the mole fraction of cationic collector in a mixed composition, flotation ceases. The flotation selectivity principally depends on the inherent differences in the surface charges of feldspar and quartz at the flotation pH values of ¡Ü2. The zeta-potential and flotation results are discussed in terms of the adsorption behavior of mixed collectors on these minerals.
