$Cu^{2+} (aq) + Fe (s) \rightarrow Cu (s) + Fe^{2+} (aq)$

Vedclass · Answer

(B) Hydrometallurgy involves the extraction of metals from their ores using aqueous solutions. For copper,low-grade ores are leached with acid or bacteria. The resulting solution containing $Cu^{2+}$ ions is treated with scrap iron or $H_2$ gas. The reaction with scrap iron is represented as: $Cu^{2+} (aq) + Fe (s) \rightarrow Cu (s) + Fe^{2+} (aq)$. Thus,option $B$ is the correct representation.

Which of the following chemical equations represents the hydrometallurgical process for the extraction of copper from its ore?
