AB  - Because of their widespread use as reagents in the flotation processing of sulphide ores, xanthates are largely found in tailings as residues. Regrettably, it is known that xanthates are not stable compounds and their decomposition generates carbon disulfide (CS2), a substance that is considered toxic. In this study, the chemical stability of xanthate was evaluated by UV/Vis spectroscopy, as a function of pH and time. The zero charge point of modified waste slag was also determined. The obtained results showed that the lowest degree of xanthate degradation is for the pH=10 and was 24.72%. For different concentrations of the KNO3 (0.1, 0.01, and 0.001 mol/dm3 ) the point of zero charge of the modified waste slag was 7.28, respectively
