The compound(s) that is(are) removed as slag during the extraction of copper is
(A) CaO
(B) FeO
(C) Al2O3
(D) ZnO
(E) NiO
Choose the correct answer from the options given below :
(A) CaO
(B) FeO
(C) Al2O3
(D) ZnO
(E) NiO
Choose the correct answer from the options given below :
(C), (D) only
(A), (B), (E) only
(A), (B) only
(B) only
The Correct Option is D
Solution and Explanation
The compound(s) that are removed as a slag during the extraction of copper is:
FeS \(\xrightarrow[]{O_2/SiO_2}\) FeSiO3 (slag) + SO2
∴ Only iron oxide (FeO) formed slag during the extraction of copper.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
