Abstract: In this paper, the fine hematite particles flotation under control dispersion is studied. The substance of this technology is combining selective dispersion and flocculate so as to lead to an incrcase in the selectivity and recovery of the fine particles under the flotation processes. The effect of pH, sodium silicate and ferrie nitrate, sodium oleate and PAMS (sulfonated polyacrylamide) on coagulation and flotation of fine hematite and quartz minerals is also investigated. A confirmatory test was carried out with mixed mineral, and better separating efficiencies were obtained.
