The final step for the extraction of copper pyrites in
The sulphide ore of copper is heated in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide. Self-reduction of CuS to Cu can be carried out in either Bessemer converter or Pierce-Smith converter.
Extraction of Copper from Copper pyrite Grade 12
The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are Crushing and Concentration The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.
In the extraction of copper from its sulphide ore the
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 sulphide ore to give copper metal.Cu2S 2Cu2O 6Cu SO2 In this process, Cu2S behaves as reducing agent.
