Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcanthite (CuSO4.5H2O), atacamite (Cu2CI(OH3)), cuprite (Cu2O), copper glance (Cu2S) and malachite (Cu2(OH)2CO3). However, 80% of the world copper production comes from the ore chalcopyrite (CuFeS2). The extraction of copper from chalopyrite involved partial roasting, removal of iron and self-reduction.
Q. Iron is removed from chalcopyrite as
- a)FeO
- b)FeS
- c)Fe2O3
- d)FeSiO3
Correct answer is option 'D'. Can you explain this answer?

Iron removal from chalcopyrite in the extraction of copper:
Chalcopyrite (CuFeS2) is the primary source of copper production, accounting for 80% of the world's copper production. The extraction of copper from chalcopyrite involves several steps, including partial roasting, removal of iron, and self-reduction. Iron is removed from chalcopyrite as FeSiO3.
Partial Roasting:
The first step in the extraction of copper from chalcopyrite is partial roasting. In this process, chalcopyrite is heated in the presence of oxygen at a temperature below its melting point. Partial roasting converts copper sulfide (CuFeS2) to copper oxide (Cu2O) and sulfur dioxide (SO2) gas.
CuFeS2 (s) + O2 (g) → Cu2O (s) + 2FeO (s) + 2SO2 (g)
Iron Removal:
After partial roasting, the next step is the removal of iron. Iron is present in the form of FeO (iron(II) oxide) in the roasted ore. To remove iron, a flux such as silica (SiO2) is added to form a slag with iron oxide. The equation for the reaction is as follows:
FeO (s) + SiO2 (s) → FeSiO3 (s)
Iron(II) oxide reacts with silica to form iron(III) silicate (FeSiO3), which is a slag. This slag is separated from the molten copper obtained in the next step.
Self-Reduction:
The final step in the extraction of copper from chalcopyrite is self-reduction. In this step, the roasted ore (Cu2O) is heated in the absence of air. The copper oxide is reduced to metallic copper (Cu), while the sulfur dioxide gas is released.
Cu2O (s) → 2Cu (s) + SO2 (g)
The metallic copper obtained is further refined and processed to obtain pure copper.
Summary:
- Iron is removed from chalcopyrite in the extraction of copper through the process of partial roasting, iron removal, and self-reduction.
- Partial roasting converts chalcopyrite to copper oxide and sulfur dioxide gas.
- Iron removal is achieved by adding a flux, such as silica, to form iron(III) silicate slag.
- Self-reduction involves heating the roasted ore in the absence of air to obtain metallic copper.
