Abstract
Provided is a method for efficiently promoting a leaching reaction of copper. Equipment for leaching copper includes a reactor for leaching reaction and a controller for oxidation-reduction potential. The reactor is configured to be provided with a leaching solution containing iodine and iron. The reactor is configured to be capable of being tightly sealed during the leaching reaction. The controller for oxidation-reduction potential is configured so that, during the leaching reaction, the oxidation-reduction potential of the leaching solution can be maintained at 500 mV (based on Ag/AgCl reference) or higher.
