Solution

In the extraction of copper from its sulphide ore,

when ore is subjected to roasting, some of it is

oxidised to $C u_{2} O$ which reacts with the remaining

$Cu_{2} S$ (sulphide ore) to give copper metal.

$C u_{2} S+2 C u_{2} O \longrightarrow 6 C u+S O_{2} \uparrow$

In this process $Cu_2S$ behaves as reducing agent
