Sphalerite is generally recovered by flotation, however, it has been established that the success of this stage is affected by surface contamination with ferric iron precipitates during grinding. In this work the flotation of sphalerite was carried out in the presence of iron precipitates 5, 25, 50 and 75 mg/L of Fe (3+) as ferric sulfate. The results show that, the cumulative flotation of sphalerite, without collector at pH 6.4, with 60 mg/L of foaming, improves, with the increase of the ferric ion, thus, with 75 mg/L and 2 minutes of flotation, cumulative recoveries are achieved 94% Infrared analysis shows absorption bands of the Zn-O bond at 1737, 1378, 1244, 1021 cm-1, in addition, the presence of the main band of the tetragonal sulfate ion at 1115 cm-1, and an absorption band corresponding to Fe-O bond of goethite at 619 cm-1.
