The Extraction of Copper Chemistry LibreTexts

Aug 21, 2020 Extracting copper from its ores. 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

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
