The effects, such as the acidity of leaching system, the temperature and the concentration of the sodium chloride, on oxidation and leaching of copper-bearing gold ores were analyzed. The results show that the sequence of sulfide ores oxidized and dissolved are pyrrhotite firstly, sulphide secondly, then chalcopyrite, pyrite lastly.

The results show that sulfite ion increases with pH value and concentration of sodium sulfite, which results in the increase of solubility of silver chloride. In the circular leaching solution, the solubility of silver chloride becomes lower with the increase of concentration of chloride ion.
