A Comparative Study of Copper Recovery from Different

01/01/2019 INTRODUCTION Hydrometallurgical copper leaching (heap leaching or dump leaching) has been used extensively for copper recovery from oxide and secondary-sulfide ores, but not for primary copper sulfides, which contain mainly chalcopyrite as copper minerals. Although they are major resources of copper, primary copper sulfides are difficult to process because of their refractory get price
