Vedclass · Answer

(C) The given reactions represent the process of self-reduction (auto-reduction) of sulphide ores.Metals like $Hg$ ($Cinnabar$,$HgS$),$Pb$ ($Galena$,$PbS$),and $Cu$ ($Copper \, glance$,$Cu_2S$) are extracted from their sulphide ores using this method.$Zn$ is extracted from its sulphide ore ($Zinc \, blende$,$ZnS$) by roasting to form $ZnO$,followed by reduction with carbon $(C)$ or carbon monoxide $(CO)$,not by self-reduction.Therefore,$X$ cannot be $Zn$.

Consider the following reactions:
$2 \, XS + 3 \, O_2 \xrightarrow{\Delta} 2 \, XO + 2 \, SO_2$
$2 \, XO + XS \xrightarrow{\Delta} 3 \, X + SO_2$
Then $X$ can not be
