उत्तर
In the extraction of copper from its sulphide ore, the metal is formed by the reduction of \[\ce{Cu2O}\] with \[\ce{Cu2S}\].
Explanation:
In the extraction of copper from its sulphide ore, the metal is formed by the reduction of \[\ce{Cu2O}\] with \[\ce{Cu2S}\]. This reaction completes with the process of auto reduction.
Chemical reaction occurring in this reaction is as follows:
\[\ce{Cu2O + 1/2 Cu2S -> 3Cu + 1/2 SO2}\]
In this process, copper appears as blister copper.
