easy
During the extraction of iron, slag produced is
A
$CO$
B
$FeSiO_3$
C
$MgSiO_3$
D
$CaSiO_3$
Solution
In extraction of iron $SiO_2$ is impurity so use basic flux.
$\mathop {CaO}\limits_{Flux} \, + \,\mathop {Si{O_2}}\limits_{{\text{Impurity}}} \, \to \,\mathop {CaSi{O_3}}\limits_{{\text{Slag}}} $
