Method of heap or dump leaching of copper from copper sulfide ore

摘要

Disclosed is a method of efficiently leaching copper not only from a readily-soluble copper ore but also a poorly-soluble copper sulfide ore partially containing or consisting of chalcopyrite and/or covellite by means of ore heap leaching under versatile conditions for actual operation. Also disclosed is a method of leaching copper from a copper sulfide ore, including leaching copper from an ore including a copper sulfide ore by heap or dump leaching with the use of a sulfuric acid solution containing ferric (III) ions and iodide ions at a total iodine concentration of 8 to 100 mg/L as a leaching solution.
