The principle ore of copper is copper pyrite and copper is extracted from this ore. During this process no external reducing agent is used so it is an example of self reduction.

Self-reduction happens in Bessemer converter reaction as

2 F e S + 3 O_{2} \to ­2 F e O + 2 S O_{2}

C u_{2} O + F e S \to C u_{2} S + F e O

F e O + S i O_{2} \to F e S i O_{3}

(removed as slag)

2 C u_{2} S + 3 O_{2} \to 2 C u_{2} O + S O_{2}

self reduction:

C u_{2} S + 2 C u_{2} O \to ­6 C u + S O_{2}

self-reduction takes place in the case of Copper.
