A) \[Fe\]
B) \[Ag\]
C) \[Al\]
D) \[Cu\]
Correct Answer: D
Solution :
In a bessemer converter, copper pyrites are oxidised to\[FeO\]and\[C{{u}_{2}}O,FeO\]is slagged off. \[C{{u}_{2}}O\]reacts with\[C{{u}_{2}}S\]left unoxidised to give \[Cu.\] \[2C{{u}_{2}}S+3{{O}_{2}}\xrightarrow[{}]{{}}2C{{u}_{2}}O+2S{{O}_{2}}\uparrow \] \[2C{{u}_{2}}O+C{{u}_{2}}S\xrightarrow[{}]{{}}6Cu+S{{O}_{2}}\uparrow \] Thus, extraction of Cu involves bessemerisa-tion
