The stability of lead ethyl xanthate (ethyl xantate ion C2H5OCS2- , EX-) on galena (PbS) surface in an alkaline medium (pH=9-12) was investigated using ATR-IR and UV spectrophotometric methods. The prolonged time of mineral treatment with ethyl xanthate solution up to 4 hours, at pH=9.2, did not affect the surface adsorbed ethyl xanthate. However, within pH range 10-12, the decomposition of surface layer occurs. The ethyl monothiocarbonate ion EMTC- (monothiocarbonateCO2S2− ) is an intermediate product of lead ethyl xanthate decomposition.
