The extraction of which of the following metals involves bessemerisation?
Options
- AFe
- BAg
- CAl
- DCu
Correct answer
D. Cu
Step-by-step solution
In a Bessemer converter, copper pyrites are oxidised to FeO and Cu ₂ O , FeO is slagged off. Cu ₂ O reacts with Cu ₂ ~S left unoxidised to give Cu . 2 Cu ₂ ~S +3 O ₂ 2 Cu ₂ O +2 SO ₂ 2 Cu ₂ O + Cu ₂ ~S 6 Cu + SO ₂ Thus, extraction of Cu involves bessemerisation.
