Question

Name the ore of Zinc other than Zinc oxide. By what process can this ore be converted into Zinc oxide?

Answer 1

The ore of Zinc other than Zinc oxide

• The minerals are extracted from their ores by various processes.
• The ores of Zinc$\left(\mathrm{Zn}\right)$ other than Zinc oxide$\mathbf{\left(}\mathbf{ZnO}\mathbf{\right)}$ and also the carbonate ore is Zinc Calamine( ${\mathbf{ZnCO}}_{\mathbf{3}}$).

The process involved in converting this ore into Zinc oxide

• The ore Zinc oxide is obtained upon calcinating the Zinc calamine.
• Calcination involves the heating process.
• Calcination is defined as the process of heating ore in a very limited amount of air below its boiling point.
• The chemical reaction occurs as follows:

$\underset{\left(\mathrm{Calamine}\mathrm{ore}\right)}{{\mathrm{ZnCO}}_3\left(\mathrm{s}\right)}\stackrel{\mathrm{Heat}}{\to }\underset{\left(\mathrm{Zinc}\mathrm{oxide}\right)}{\mathrm{ZnO}\left(\mathrm{s}\right)}+{\mathrm{CO}}_2\left(\mathrm{g}\right)$
