Hint: To answer this question, you should recall the concept of the froth flotation process. This process is used for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer.

The cyanide extraction process of silver from argentite ore is as follows, Ag(2)S+2CN^(-) + O(2) to 2[Ag(CN)(2)]^(-) +SO(2) Zn +2[Ag (CN)(2)]^(-) to [Zn(CN)(4)]^(2-) +2Ag In the first reaction, oxygen in O(2) is reduced from 0 to –2. So it is an oxidising agent. Similarly in the second reaction zinc is oxidised, so it is a reducing agent.
