(c) How is zinc extracted from its carbonate ore (calamine)? Explain with equations.

Solution:

(c) Calamine ore decomposes into zinc oxide and carbon dioxide when heated rapidly in the absence of air.

ZnCO3 → ZnO + CO2

The zinc oxide is then heated with carbon to generate zinc metal.

ZnO + C → Zn + CO
