Question

how is copper extracted from the sulphide ? give ist chemical equation​

Answer 1

Answer:

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 contain valuable metals such as gold and silver which can be recovered in the native state.

Hope it's help you.....

Answer 2

Answer:

copper is extracted from its sulphide ore by the process of roasting . in this process the sulphide is heated in the presence of excess air to convert it into oxide ore. now it is heated again to for copper

CuS + O2-----> Cu2O

Cu2O + CuS----> Cu+ SO2
