Vedclass · Answer

(B) . Self reduction: Used for metals like $Cu$ (from $Cu_2S$) and $Pb$ (from $PbS$). Thus,$A-P, R$.$B$. Carbon reduction: Used for metals like $Pb$ (from $PbO$) and $Cu$ (from $CuO$). Thus,$B-P, R$.$C$. Complex formation and displacement by metal: Used for $Ag$ (MacArthur-Forrest cyanide process). Thus,$C-Q$.$D$. Decomposition of iodide: Used for refining of $B$ (Van Arkel method). Thus,$D-S$.Matching: $A-P, R; B-P, R; C-Q; D-S$. Therefore,the correct option is $B$.

Column $I$	Column $II$
$A$. Self reduction	$P$. Lead
$B$. Carbon reduction	$Q$. Silver
$C$. Complex formation and displacement by metal	$R$. Copper
$D$. Decomposition of iodide	$S$. Boron

Match the extraction processes listed in Column $I$ with metals listed in Column $II$:

Column $I$ Column $II$

$A$. Self reduction $P$. Lead

$B$. Carbon reduction $Q$. Silver

$C$. Complex formation and displacement by metal $R$. Copper

$D$. Decomposition of iodide $S$. Boron
