| Zusammenfassung: | A method of leaching copper sulfide ore includes leaching copper from copper sulfide ore using a sulfuric acid solution comprising iodide ion and iron (III) ion surplus to the iodide ion as a leaching solution; reducing iodine in a solution obtained after the leaching step to less than 1 mg/L by an activated carbon treatment; and oxidizing iron (II) ion or newly added iron (II) ion in a solution obtained after the iodine reduction step by using iron oxidizing microbes to recover iron (III) ion. |
