Give the reaction involved during the extraction of zinc from its ore by
a. Roasting of zinc or b. Calcination of zinc ore
OR
How are roasting and calcination used in the extraction of zinc? Explain with the help of chemical equations. After these processes is reduction necessary to obtain zinc? Why

Text Solution

Verified by Experts

a.`2ZnS+3O_(2)to2ZnO+2SOS_(2)`
b `ZnCO_(3)toZnO+CO_(2)`
After roasting and calcination, oxide of zinc is obtained. Hence, its reduction is necessary to obtain zinc.
