Calcination followed by carbon reduction is applicable for the extraction of metal from :

Options:

Answer:

Solution:

Calcination converts carbonate ore (like calamine, ZnCO₃) to oxide (ZnO). Carbon reduction then reduces the metal oxide to the metal. This two-step process is suitable for moderately reactive metals like zinc.

1. Calcination: ZnCO₃(s) $h e a t$ ZnO(s) + CO₂(g)

2. Carbon Reduction: ZnO(s) + C(s) $h e a t$ Zn(s) + CO(g)
