Vedclass · Answer

(B) In the extraction of $Zn$ from its ore (usually $ZnO$),the reduction is carried out by heating with coke $(C)$.Since $Zn$ has a low boiling point $(907 \ ^\circ C)$,it is obtained in the vapor state.The metal is then recovered by condensation of the metal vapors.Because the metal itself is volatile and can be separated from the non-volatile impurities by distillation,the addition of a flux to form a slag is not required.

In the metallurgy of $Zn$,flux is not used because
