How is zinc extracted from its ore?

Answer

Zinc is extracted from its ore by calcination to remove the sulphur converting zinc to an oxide. The next step is to smelt the particular oxide with carbon where it is combined with oxygen to form a gas. Finally, the deoxidised metal distils in vapour and is then precipitated again into the solid form after extraction.
