The concentrations of S2O3 2- and SO3 2- were measured in gold leaching systems,including thiosulfate system,polysulfide system and the modified lime sulfur synthetic solution(ML)system in the process of chemical reaction.The interactions among S2O3 2- ,SO3 2-and S 2-were discussed.The behavior mechanism of sulfur-bearing reagents was proposed to describe the process reactions and their Gibbs free energy.The proper quantity oxygen and SO3 2- reduce decomposition of S2O3 2-and react with sulfur derived from the decomposition of SX 2- .So,SO3 2-ions have action to stabilize sulfur-bearing system and are favorable to leach gold.
