ROLE OF OXYGEN IN DUMP LEACHING

摘要: ABSTRACT As invaluable as oxygen is in many hydrometallurgical processes, dump leaching of copper no exception. Without the availability dumps, pyrite cannot be oxidized to provide required ferric iron and acid for leaching. Moreover, without oxygen, primary secondary minerals solubilized. Finally, bacterial activity dumps would retarded resulting poor extraction. Accordingly, presence essential every effort must made this ingredient recipe. This paper presents important role that plays copper. The theoretical practical aspects sulfide are presented. Similarly, discussed. efforts have been present engineering, technical economic design operation providing sustaining maximum system.
