Which following compound acts as a flux in extraction of copper from copper pyrites
- A \(\mathrm{CaSiO}_{3}\)
- B \(\mathrm{FeO}\)
- C \(\mathrm{FeSiO}_{3}\)
- D \(\mathrm{SiO}_{2}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{SiO}_{2}\)
Step-by-step Solution
Detailed explanation
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 \(\mathrm{FeSiO}_{3}\).
The flux used is \(\mathrm{SiO}_{2}\) and slag formed is \(\mathrm{FeSiO}_{3}\).
