Question
How is the following metallic oxide reduced? Write the equation:
Zinc oxide
Solution
It is reduced by a carbon reduction process using a suitable reducing agent, carbon (C).
ZnO and Coke are heated in retort by producer gas (CO + N2) to get zinc spelter.
\[\ce{ZnO(s) + C(s) ->[1400^\circ C] \underset{(Zinc spelter)}{Zn(s)} + CO(g)}\]
