Vedclass · Answer

(D) $1$. $Pb$ (Lead) is extracted from Galena $(PbS)$ primarily by self-reduction of its oxide $(PbO)$ with the remaining sulfide $(PbS)$.$2$. $Cu$ (Copper) is refined using the poling process,where molten copper is stirred with green wood poles to reduce copper$(I)$ oxide $(Cu_2O)$ to copper metal.$3$. $Ag$ (Silver) is extracted via the Mac-Arthur Forrest cyanide process,which involves leaching silver ore with a dilute solution of $NaCN$ or $KCN$ in the presence of air.$4$. Since all these processes are standard metallurgical techniques for the respective metals,the correct option is $D$.

List-$I$	List-$II$
$A$. Calcination	$1$. Galena
$B$. Roasting	$2$. Magnetite
$C$. Magnetic separation	$3$. Pyrometallurgy
$D$. Carbon reduction of metal oxide	$4$. Malachite

Select the correct option regarding the processes used during metal extraction from their ores.
