Which following compound acts as a flux in extraction of copper from copper pyrites
Which following compound acts as a flux in extraction of copper from copper pyrites
$\mathrm{CaSiO}_{3}$
$\mathrm{FeO}$
$\mathrm{FeSiO}_{3}$
$\mathrm{SiO}_{2}$
Solution
Copper is extracted from the ore copper pyrite by smelting in a blast furnace.
The flux used is $\mathrm{SiO}_{2}$ and slag formed is $\mathrm{FeSiO}_{3}$.
