摘要
An object of the present invention is to provide a method of efficiently leaching copper from copper sulfide ores containing chalcopyrite at room temperature. A method of recovering copper from copper sulfide ores, characterized by comprising: using a sulfuric acid solution having a chloride ion concentration adjusted to 6 g/L or more but less than 18 g/L and a pH adjusted to 1.6 or more but less than 2.5 as a leaching solution; and carrying out copper leaching with the addition of a chloride ion-resistant sulfur-oxidizing bacterium to the leaching solution, when recovering copper from copper sulfide ores containing chalcopyrite, is provided.
