Q. Which among the following is used as flux in the extraction of iron from oxide ores?

AP EAMCETAP EAMCET 2020

Solution:

Lime stone $\left( CaCO _{3}\right)$ used in the extraction of $Fe$ from haematite in blast furnace get decomposed to $CaO$, which removes silicate impurity (gangue) of the ore as molten slag.
$CaCO _{3} \xrightarrow{A}CaO + CO _{2}$
$CaO + SiO _{2} \xrightarrow{\Delta} CaSiO _{3}$
