摘要：A new organic leaching agent (3YL) was applied the process of leaching gold in our recent research project. Compared to conventional cyanidation method, studies show that 3YL can serve as an alternative and non-toxic leaching agent, which has several advantages over cyanides including leaching speed, environmental effect, and other aspects. In this paper, the temperature and the acidity of the dissociation process for 3YL were investigated. The results show that within a certain range, the temperature and acidity have significantly positive effect on the dissociation. Meanwhile, the dynamic process of gold leaching was also studied. The experimental data are consistent with the existing model, and the results show that the process is controlled by external diffusion.
