Highlights Two gold ores were subjected to iodide/iodine leaching. The carbonaceous ore showed only 20% gold extraction. Gold extraction from the oxide ore reached 89% in 24 h. A power law rate equation was applied to model the gold extraction kinetics. Gold leaching rate was first order with respect to tri-iodide concentration.

When the leaching volume reached 10 m 3 /t ore, the CuT recovery of the JX Iodine Process for sample A increased linearly to 69.7% (56.0% higher than blank), while sample B increased to 52.7% (33.2% higher than blank) with a slight slowdown. In general, the leaching kinetics of primary-sulfide ore which is represented by chalcopyrite is slow.
