Thermodynamics and Electrochemistry of the Interaction of Sphalerite with Iron (II)-Bearing Compounds in Relation to Flotation

The flotation recovery of sphalerite depends on the inorganic reagents concentrations in liquid phase suspension and pH. This paper presents results studies interactions iron (II) containing ions with surface water solutions at different pH levels. thermodynamic electrochemical were carried out to analyze possible sulfate a environment relate them potassium butyl xanthate sodium dibutyl dithiophosphate. calculations revealed possibility interaction hydrolysis products. effect hydroxide concentration precipitation hydroxides was examined. findings showed that = 8 there no precipitates observed FeSO4. Increasing from 12 resulted formation hydroxides. potentiometric slightly alkaline Fe2+ FeOH+ cations are potential-determining. In conclusion, tests thiol collectors show activation sulphate low dosage 12. is evident by higher these conditions.
