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. Partial roasting of chalcopyrite produces
- a)Cu2S and FeO
- b)Cu2O and FeO
- c)CuS and Fe2O3
- d)Cu2O and Fe2O3
Correct answer is option 'A'. Can you explain this answer?

Partial roasting of chalcopyrite produces Cu2S and FeO
Partial roasting is a process in which a metal sulfide ore is heated in the presence of limited oxygen. It is used to convert the sulfide ore into an oxide or a mixture of oxides. In the case of chalcopyrite (CuFeS2), partial roasting results in the production of copper sulfide (Cu2S) and iron oxide (FeO).
Explanation:
- Chalcopyrite is a copper iron sulfide mineral that is the most abundant copper ore. It contains both copper and iron, and the aim of the partial roasting process is to separate these two metals.
- During partial roasting, chalcopyrite is heated in a controlled environment with limited oxygen. This controlled heating causes the sulfur in chalcopyrite to react with oxygen to form sulfur dioxide (SO2), which is released as a gas.
- The reaction can be represented as follows:
2CuFeS2 + 3O2 → 2Cu2S + 2FeO + 2SO2
- In this reaction, the chalcopyrite is converted into copper sulfide (Cu2S) and iron oxide (FeO). The sulfur in chalcopyrite combines with oxygen to form sulfur dioxide, while the copper and iron remain in their respective sulfide and oxide forms.
- Cu2S is the copper sulfide product obtained during partial roasting. It is a black solid with a high melting point and is further processed to obtain pure copper.
- FeO is the iron oxide product obtained during partial roasting. It is a black solid and can be further processed or used as a source of iron.
- The other options mentioned in the question (Cu2O and FeO, CuS and Fe2O3, Cu2O and Fe2O3) are incorrect because they do not represent the products of partial roasting of chalcopyrite. The correct products are Cu2S and FeO.
In summary, the partial roasting of chalcopyrite produces copper sulfide (Cu2S) and iron oxide (FeO). This process is an important step in the extraction of copper from chalcopyrite ore.
