Question

Zinc metal which can be refined by distillation method ?

Answer 1

ZInc is present as the following ore: 

# Zinc blend= ZnS
# Calamite= ZnCO₃
#Zincite=ZnO

In all these ore the impurity present have higher boiling point compared to that of Zinc.Hence Zinc evaporates soon,when the ore solution is heated.

This process is very useful for low boiling metals like Zinc,and mercury.The impure metal is evaporated to obtain pure metal as distillate.
