Industrial applications of Reduction reaction is in batteries and cells. In dry cell, the zinc case serves as the anode and reduction of MnO₂ takes place. Reaction is-

{tex}Zn + 2MnO_2 + 2NH^{4+}\to Zn^{2+} + Mn_2O_3 + 2NH_3 + H_2O {/tex}

Dry cells cannot be recharged, so they are one-use only.

Industrially reduction reaction is used in blast furnace, used for smelting to produce iron. Iron is produced by chemically reducing iron oxide to molten iron.
3Fe₂O₃ + CO → CO₂ + 2Fe₃O₄
Fe₃O₄ + CO → CO₂ + 3FeO
FeO + CO → CO₂ + Fe
