Abstract

The present invention provides a method of leaching copper from a copper sulfide ore, wherein operating costs and environmental impacts can be effectively reduced. The present invention is a method of leaching copper from a copper sulfide ore by a process of leaching a layer of stacked ores, wherein the leaching solution containing Fe (III) ion and other leaching solution containing iodide ion are fed through routes independent of each other to a layer of stacked ores containing a copper sulfide ore.

Claims (2)

1. A method of leaching copper from a copper sulfide ore by a process of leaching a layer of stacked ores, wherein a leaching solution containing Fe (III) ion and other leaching solution containing iodide ion are fed through routes independent of each other to a layer of stacked ores containing a copper sulfide ore.

2. A method of leaching copper from a copper sulfide ore according to claim 1 , wherein a major component of the ore containing the copper sulfide ore is chalcopyrite.
