Question

Select a suitable process that is followed to extract Zinc $\text{(}Zn)$ from $ZnC{O}_3$ ore.

• A. Calcination
• B. Roasting
• C. Heating
• D. Electrolytic Refining

Answer 1

The correct option is A Calcination

In the process of calcination, carbonate ores are converted into oxides by strongly heating it in a limited supply of air. This process is known as calcination. These oxides are further reduced to give the required metal.

$ZnC{O}_3\to ZnO+C{O}_2$

Here, zinc oxide is formed in this reaction which is further reduced to obtain Zn.
