A) Fe
B) Ag
C) \[Al\]
D) Cu
Correct Answer: D
Solution :
Copper metallurgy involves bessemerisation. In bessemer convenor, the impurities of ferrous oxide forms slag with silica and copper oxide is reduced to give blister copper. \[\underset{\begin{smallmatrix} Ferrous \\ \,\,\,oxide \end{smallmatrix}}{\mathop{FeO}}\,+Si{{O}_{2}}\xrightarrow{{}}\underset{Slag}{\mathop{FeSi{{O}_{3}}}}\,\] \[C{{u}_{2}}S+2C{{u}_{2}}O\xrightarrow[{}]{{}}6Cu+S{{O}_{2}}\]You need to login to perform this action.
