Method for leaching copper and gold from sulphide minerals that comprises contacting the mineral with a solution containing chlorine, copper and iron ions with an oxidizing agent.
Method for the separation of the iodine absorbed by an activated carbon, where a separation solution is passed through said activated carbon, the oxidation-reduction potential of a post-separation solution is less than or equal to 180 mv, and is determined the completion of the separation when the pH is greater than or equal to 1.5 and the ratio of a reducing agent that has not reacted reaches more than 60%.
