Zinc is a metal in the middle of the activity series.

So it is found either in sulphide or carbonate ore..

For sulphide--

Zinc sulphide is first converted into oxide as it is easier to obtain metals from it's oxides. For a sulphide ore ,zinc sulphide is heated in the presence of oxygen,this is called roasting

2ZnS + 3O2 —————-2ZnO + 2SO2

For Carbonate--

Zinc is heated in absence oxygen.This process is called calcination.

ZnCO₃ (on calcination) → ZnO + CO₂

Then zinc oxide is reduced to give Zn.

ZnO+C----Zn + Co

Hope it helped ❤️
