Innovations: Introduction to Copper: Mining Extraction
The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate Today, more than 13% of all "new" copper is produced from leachates, which are normally concentrated using solvent extraction (SX) and stripped of their copper content by Answer:In the extraction of copper from its Sulphide Ore, when ore is subjected to roasting some of it is oxidised to Cu2O which reacts with the remaining Cu2S to give copper metal In this process, Cu2S behaves as reducing agent 2Cu2S+3O2+heat→2Cu2O(s)+2SO2(g) 2Cu2O+Cu2S+heat→ 6Cu(s)+SO2(g) In electrolytic refining of copper, the impurities left behind at anode called anode mud How is copper extracted from its sulphide ore?
