• Extraction Of Copper Mining, Concentration, Smelting

Thecopper 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 leaves. This causes the final product to have a very …

• METALLURGYOF COPPER EXTRACTION OF COPPER BLISTERCOPPER

Blast of air converts Cu2S partly into Cu2O which reacts with remaining Cu2S to give molten copper. 2Cu2S + 3O2 è 2Cu2O + 2SO2. 2Cu2O + Cu2S è 6Cu + SO2. The copper so obtained is called "Blister copper" because, as it solidifies, SO2 hidden in it escapes out producing blister on its surface.
