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

Options

A. FeS
B. CO
C. `Cu_2S`
D. `SO_2`

Answer

C

Explanation

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.
