Abstract

The effect of sulfite interaction with GALENA on the mechanism of potassium isoamyl xanthate (KIAX) synthesized ADSORPTION onto GALENA surfaces has been studied in situ using ELECTROCHEMICAL POTENTIAL; FTIR spectra and SEM have been used to identify the mechanism of interaction between sulfite and GALENA surfaces. Activated GALENA with copper sulfate (10-4 M) has been investigated at pH 9.12 and potassium isoamyl xanthate (3×10-3 M) concentration. Oxidised GALENA surfaces have relatively low concentration of adsorbed xanthate and high potential (Eopt=-89 mV); adsorbed colloidal (Pb-IAX, 1,123.08 cm-1) is found even at high xanthate concentration, colloidal lead oxide/hydroxide particles have been imaged after 10-4M lead sulfate addition at pH 9.12. The behavior of this system is consistent with ion exchange between xanthate and hydroxide followed by oxidation to dixanthogen (X2, 1,273.56 cm-1) and diffusion of this species across the surface.
