In the extraction of Cu from its sulphide ore, the metal is formed by reduction of `Cu_(2)O` with

A

FeS

B

CO

C

`Cu_2S`

D

`SO_2`

Text Solution

Verified by Experts

The correct Answer is:
C
In the extraction of copper from its sulphide ore, the metal is formed by the reduction of `Cu_2O` with `Cu_(2)S`.This reaction completes with the process of autoreduction.
Chemical reaction occurring in this reaction is as follows `Cu_(2)O + (1)/(2) Cu_(2)S rarr 3Cu + (1)/(2)SO_(2)`
In this process, copper appears as blister copper.
