Explanation:

The extraction of silver involves in cyanide process are

(i) Ag

2

S+2CN

+O

2

→23[Ag(CN)

2

]

+SO

2

(ii) [Ag(CN)

2

]

+Zn→[Zn(CN)

4

]

2−

+Ag

Thus, in (i) O

2

−act as oxidising agent (oxidise sulphide to SO

2

) and in (ii) Zn act as reducing agent (reduce Ag

+

to Ag).
