The Extraction of Copper Chemistry LibreTexts

Aug 21, 2020 The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Extraction Of Copper Mining, Concentration, Smelting

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. \(Cu^{2}S + O^{2} → 2Cu + SO^{2}\) The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2

Extracting copper. Extracting copper.

Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.

Dec 20, 2013 An analysis of energy usage in the production of refined cathode copper was made from mining ore to cathode copper. In mining copper ore the greatest energy consumers are ore hauling and blasting. Another important factor is the “recovery efficiency” of the metallurgical processes used to extract the copper. The mining and mineral concentrating energies are directly proportional to the

advantages and disadvantages The Only Good Metal~Copper

A disadvantage of copper is that it costs a lot of money because it takes a lot of energy to dig the ore and to extract copper. Another disadvantage is that it is non-renewable because it can't be grown or produced. Finally, the last disadvantage is that it can broken easily. Know we know that copper has some advantages and disadvantages of

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
