The cationic flotation of quartz was carried out from an artificial mixture (1:1 by weight) of fine grained (-10 ¦Ìm) quartz and hematite, using hexylamine acetate (HAA) and dodecylamine acetate (DAA) as collectors. Selective flotation of quartz was possible in the pH range 9-10 using HAA. The adsorption densities of DAA and HAA on quartz and hematite were measured at pH 9.8 and the relation between the flotation behavior of both minerals and the surface coverage of collectors was established. Complete flotation of quartz and hematite required a surface coverage (¦È) of DAA of ?100% at pH 9.8, while complete flotation of quartz took place at ¦È ? 10% with HAA. The flotation behavior with DAA was explained by considering the adsorption of undissociated free amine. Zeta potential measurements were incorporated to interpret the difference in the adsorption behavior of both collectors on quartz and hematite.
