Abstract Electrochemical oxidation of pyrite (FeS 2 ) in aqueous electrolytes has been investigated using electrochemical techniques, in situ Fourier transform infrared spectroscopy (FTIR), ex situ X-ray photoelectron spectroscopy (XPS) and ion chromatography (IC). The results show that when pyrite is polarised in the potential region of −0.35 to 0.25 V versus SCE in 1 M HCl at sweep rates ≥30 mV s −1 , the redox process is a reversible electrochemical adsorption/desorption, whereas at sweep… CONTINUE READING
