On the extraction of iron, the slag produced is
Options

(b) FeSiO₃
(c) MgSiO₃
(d) CaSiO₃
Correct Answer:
CaSiO₃
Explanation:
In the extraction of iron, limestone which acts as flux, decomposes at 1073 K to form CaO which than combines with silica to form slag. CaCO₃ → CaO + CO₂. CaO + SiO₂ → CaSiO₃ (slag).
