Surface Modification of Jamesonite During Flotation; Effect of the Presence of Ferric Ion Conference Paper uri icon

abstract

  • In the present study, the analysis of the surface modification of jamesonite during flotation with and without a collector, in the presence of Fe3 ions, was approached. It was found that the use of 25 mg/L of ferric ion acts as an activator during the collectorless flotation of jamesonite, obtaining a 79%25 w/w separation. Higher concentrations (75 mg/L of Fe3 ) do not increase efficiency, even though in the presence of 60 mg/L of xanthate, the cumulative flotation is 64%25 w/w. This is due to the surface modification, detecting the increase in the intensity of the absorption bands of lead oxide (PbO) in 419 cm−1, of lead dioxide (PbO2) in 617 cm−1, of goethite (α-FeOOH) in 881 cm−1, of antimony oxides, and the formation of bidentate sulfates in coordination with the metal with four absorption bands identified by infrared. © 2022, The Minerals, Metals & Materials Society.
