<p><P>PROBLEM TO BE SOLVED: To provide a method in which, under conditions with versatility on a practical operation level in laminated body leaching for copper sulfide ore, copper is efficiently leached from copper sulfide ore comprising not only easily soluble copper ore but also comprising sparingly soluble brass ore and covellite partially or wholly. <P>SOLUTION: The method for leaching copper from copper sulfide ore is characterized in that, using a sulfuric acid solution comprising iron (III) ions and iodine ions in which the total iodine concentration is 8 to 100 mg/L as a leachate, copper is leached from ore including copper sulfide ore by a laminated body leaching method. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
