Question

How is copper extracted from its sulphide prw? give its chemical equation ​

Answer 1

hyy mate ✌️

Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting. The obtained oxide is then reduced with carbon or any other suitable reducing agent to obtain the metal. 

 2Cu2S + 3O2 → 2Cu2O + 2SO2

 2Cu2O + Cu2S → 6Cu + SO2

The obtained metal is then purified by electrolytic refining. 

Following reactions take place at anode and cathode

Anode : Cu ---------> Cu+2 + 2e-

cathode : Cu+2 + 2e- --------> Cu

hope it will help you ❣️
