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

\mathrm{Cu}_2 \mathrm{O}, \mathrm{FeO}

is slagged off.

\mathrm{Cu}_2 \mathrm{O}

reacts with

\mathrm{Cu}_2 \mathrm{~S}

left unoxidised to give Cu .

2 \mathrm{Cu}_2 \mathrm{~S}+3 \mathrm{O}_2 \longrightarrow 2 \mathrm{Cu}_2 \mathrm{O}+2 \mathrm{SO}_2 \uparrow

2 \mathrm{Cu}_2 \mathrm{O}+\mathrm{Cu}_2 \mathrm{~S} \longrightarrow 6 \mathrm{Cu}+\mathrm{SO}_2 \uparrow

Thus, extraction of Cu involves bessemerisation.
