Question

The extraction of which of the following metals involves bessemerisation?

• A. $Fe$
• B. $Ag$
• C. $Al$
• D. $Cu$

Answer 1

Answer: (D)

$Cu$

Answer 2

Copper metallurgy involves bessemerisation. In Bessemer convertor the impurities of ferric oxide forms slag with silica and copper oxide is reduced to give blister copper. $FeO+SiO_2 \to \underset{\text{slag}}{FeSIO_3}$ $Cu_2S + 2Cu_2O \to 6Cu + SO_2$
