Correct Answer - B
Bessemerisation is used in the extraction of copper from copper matte.
The following reactions takes place:
`2FeS+3O_(2)to2FeO+2SO_(2)uarr`
`FeO+SiO_(2)tounderset("(Slag)")(FeSiO_(3))`
`2Cu_(2)S+3O_(2)to2Cu_(2)O+2SO_(2)uarr`
`2Cu_(2)O+Cu_(2)Sto6Cu+SO_(2)uarr`
The molten copper is allowed to cool. During cooling, dissolved `SO_(2)` comes out in the form of blisters, so it is called blister copper.
