Abstract:Effects of NH3, Cu(2+) and Cu ion, pH and stirring intensities on the stability of thiosulfate were investigated to find out the regularities of thiosulfate consumption during leaching of copper-bearing gold ore. Results showed that ammonia is indispensable for gold leaching by thiosulfate from any material, and cupric ions are needed only for the materials without copper.Reasonable leaching processes for different materials are recommended.
Keywords:Thiosulfate  Leaching  Gold ore  Decomposition
