<p><P>PROBLEM TO BE SOLVED: To provide a method for efficiently leaching copper from copper sulfide ore mainly containing chalcopyrite and enargite under a versatile condition at an actual operational level. <P>SOLUTION: In the method for leaching the copper from the copper sulfide ore, the copper is leached from the copper sulfide ore by using sulfuric acid solution containing iodine ion and iron(III) ion in an excessive amount to the iodine ion as the leaching solution, or by using the leaching solution containing a hydrosoluble ligand which can stabilize the iron(III) ion of chloride ion etc. and is further added to the above compositions. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
