Describe the role of
`SiO_(2)` in the extraction of copper from copper matte.
Write the chemical equations for the involved reactions.

Text Solution

Verified by Experts

During smelting and bessemerisation, the impurity, i.e. ferrous sulphide, is oxidised to ferrous oxide which is then reacted with silica (flux) to form slag (ferrous silicate).
`underset("Oxide")(FeO) + underset("Flux")(SiO_(2)) to underset("Ferrous silicate(Slag)")(FeSiO_(3))`
