Given below are the steps for extraction of copper from its ore. The balance reaction involved in reduction of copper(l) oxide with copper(l) sulphide is given in the reaction below. \[ \mathbf{2} C u_{2} \boldsymbol{O}+\boldsymbol{C} \boldsymbol{u}_{2} \boldsymbol{S} \stackrel{\text {Heat}}{\longrightarrow} \boldsymbol{6} \boldsymbol{C} \boldsymbol{u}+\boldsymbol{S} \boldsymbol{O}_{2} \] This reaction is known as:
- A. auto-reduction
- B. catalytic- reduction
- C. acid reduction
- D. none of these
Step-by-step solution
In the given reaction, copper(I) oxide is reduced by copper(I) sulfide without an external reducing agent; this process is known as auto-reduction (or self-reduction). It is a key step in the extraction of copper from its ore.
