Question

The extraction of which of the following metals involves bessemerisation?

• A. Fe
• B. Ag
• C. Al
• D. Cu

Answer 1

The correct option is D Cu

The extraction of copper involves bessemerization.
In the extraction of copper from its sulphide ore, the metal is formed by reduction of $C{u}_{2}O$ with $C{u}_{2}S$.
The sulphide ore of copper is heated in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide.
Self-reduction of CuS to Cu can be carried out in either Bessemer converter.
$2C{u}_{2}S+3O_2\to 2C{u}_{2}O+2S{O}_2$
$2C{u}_{2}O+C{u}_{2}S\to 6Cu+S{O}_2$
