Abstract

Abstract

Degradation of several different single/mixed xanthates under natural conditions and after adsorption of sulfide ore was analyzed. The effects of xanthate concentration, different ratios of mixed xanthate and adsorption of sulfide ore on the degradation of xanthate were investigated, and the corresponding degradation kinetic equation was established. The results show that under natural degradation conditions, whether increasing the ratio of ethyl xanthate or amyl xanthate in the mixed xanthate, it is more difficult to degrade than the natural degradation of a single xanthate. Increasing the ratio of amyl xanthate can accelerate its natural degradation rate after the action of sulfide ore. It is obvious that the degradation rate of the mixed xanthate after adsorption of sulfide ore is significantly greater than of the xanthate under natural conditions.After the adsorption of sulfide ore, the low sulfur content has a higher degradation rate compared with the high sulfur content. The degradation process of single xanthate with different concentrations, mixed xanthate with different ratios under natural conditions and mixed xanthate after the adsorption of sulfide ore are basically following the first-order kinetic equation.
