Copper Smelting an overview ScienceDirect Topics

W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001 4 The Future. The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching “oxide” and supergene sulfide

Electrolysis of copper(II) sulfate solution Experiment

Bubbles of gas (oxygen) are formed at the anode. Cathode reaction: Cu 2+ (aq) + 2e- → Cu(s) Anode reaction: 2H 2 O(l) → O 2 (g) + 4H + (aq) + 4e-With carbon (graphite) electrodes, the oxygen usually reacts with the anode to form CO 2. If copper is used for the electrodes, the copper anode dissolves. The reaction is the reverse of the

In-situ leaching recovery of copper: what’s next

Solution mining is conveniently divided into three main categories: heap leaching, dump leaching, and in situ leaching. In situ leaching (ISL) involves the application of a specific lixiviant to dissolve en masse minerals within the confines of a deposit or in very close proximity to its original geologic setting.
