medium
In the extraction of copper, metal is formed in the Basserner converter due to reaction
A
$Cu_2S + 2Cu_2O \to 6Cu + SO_2$
B
$Cu_2S \to 2Cu + S$
C
$Fe + Cu_2O \to 2Cu + FeO$
D
$2Cu_2O\to 4Cu + O_2$
Solution
In the extraction of copper, metal is formed in the Bessemer converter due to self reduction.
Reaction: $Cu _2 S +2 Cu _2 O \rightarrow 6 Cu + SO _2$
