उत्तर
Bassemerisation is used in the extraction of copper.
Explanation:
Bessemerisation is used in the extraction of copper from copper matte.
The following reactions takes place:
\[\ce{2FeS + 3O2 -> 2FeO + 2 SO2\uparrow}\]
\[\ce{FeO + SIO2 -> \underset{\text{(Slag)}}{FeSiO}}\]
\[\ce{2Cu2S + 3O2 -> 2Cu2O + 2SO2\uparrow}\]
\[\ce{2Cu2O + Cu2S -> 6Cu + SO2\uparrow}\]
The molten copper is allowed to cool. During cooling, dissolved SO2 comes out in the form of blisters, so it is called blister copper.
