Question
Self-reduction of Cu2S to Cu can be carried out in.
Options
A.bessemer convertor
B.blast furnace
C.both (A) and (B)
D.none of these
Solution
Matte is obtained in blast furnace and that contains mostly Cu2S and FeS. It is transferred to bessemer converter where self reduction takes place according to the following reactions.
2Cu2S + 3O2 → 2Cu2O + 2SO2 ; 2Cu2O + Cu2S → 6Cu + SO2.
2Cu2S + 3O2 → 2Cu2O + 2SO2 ; 2Cu2O + Cu2S → 6Cu + SO2.
