Which of the following reaction(s) do(es) not occur in Bessemer's converter ?
A
$2Cu_2S + 5O_2 \rightarrow 2CuSO_4 + 2CuO$
B
$2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2 \uparrow $
C
$2CuFeS_2 + O_2 \rightarrow Cu_2S + 2FeS + SO_2$
D
$FeO + SiO_2 \rightarrow FeSiO_3$
Solution
In the extraction of copper, following reactions take place in Bessemer converter:
$2 Cu _2 S +3 O _2 \rightarrow 2 CuO +2 SO _2$
$Cu _2 S +2 Cu _2 O \rightarrow 6 Cu + SO _2$
and
$2 Cu _2 S +5 O _2 \rightarrow 2 CuSO _4+2 CuO$
$2 Cu _2 S + Cu _2 SO _4 \rightarrow 4 Cu +2 SO _2$
and
$FeO + SiO _2 \rightarrow FeSiO _3$
