[CPMT 2000]
Options:
A) $ 4Cu_2O+FeS\to 8Cu+FeSO_4 $
B) $ Cu_2S+2Cu_2O\to 6Cu+SO_2 $
C) $ 2Cu_2O+FeS\to 4Cu+Fe+SO_2 $
D) $ Cu_2S+2FeO\to 2Cu+2FeCO+SO_2 $
Show Answer
Answer:
Correct Answer: B
Solution:
In Bessemer converter copper sulphide is partially oxidised to cuprous oxide which further reacts with remaining copper sulphide to form copper and sulphur dioxide.
