Which type of copper is formed by the following reactions?
2Cu2S + 3O2 \(\rightarrow\)6Cu + SO2
Which type of copper is formed by the following reactions?
2Cu2S + 3O2 \(\rightarrow\)6Cu + SO2
Blister copper
Copper crisp
Reduced copper
Copper slag
The Correct Option is A
Solution and Explanation
The correct answer is option (A) : Blister copper
In the reaction, the oxidation number of copper decreases from +1 in Cu2O or Cu2S to 0in copper metal. Therefore, copper is reduced and it is oxidizing agent or oxidant.Further the oxidation number of S increases from -2 in Cu2S to +4 in SO2 , therefore sulfur is oxidised.

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
