    Abstract: Kinetic models can be used to characterize the flotation process. In this paper, three primary parameters, namely, distribution of flotation rate constant f(K), order of flotation process n and ultimate recovery R∞ are presented to perform analysis of flotation kinetics. The flotation rate constant f(K) is aAt the given reagent and operating conditions, floc flotation increases the floatability of the galena and sphalerite fines over 30% ~ad 50% in the range of pH 5 to 8, respectively, in comparison to the corresponding conventional flotation. Clearly, floc flotation is an effective means of recovering galena and sphalerite fines.
