A

CO

B

`FeSiO_3`

C

`MgSiO_3`

D

CaSiO_3`

Text Solution

Verified by Experts

The correct Answer is:
D
In the extraction of iron, lime stone which acts as flux, decomposes at 1073 K to form CaO which then combines with silica to form slag.
`CaCO_3` `rarr^(1073 K)` CaO + `CO_2`
CaO + `SiO_2` `rarr` `CaSiO_3`
