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_(2)S`

D

`SO_(2)`

Text Solution

Verified by Experts

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