Question

Extraction of copper from copper pyrite $\left(CuFe{S}_2\right)$ involves :

• A. crushing followed by concentration of the ore by froth-flotation
• B. removal of iron as slag
• C. self-reduction step to produce 'blister copper' following evolution of $S{O}_2$
• D. refining of 'blister copper' by carbon reduction

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A crushing followed by concentration of the ore by froth-flotation
B removal of iron as slag
C self-reduction step to produce 'blister copper' following evolution of $S{O}_2$
D refining of 'blister copper' by carbon reduction

Hence from the above diagram shows that all options are correct.
