Vedclass · Accepted Answer

Galena

Vedclass · Answer

(A) The correct answer is $(A)$.Froth-flotation is a process specifically used for the concentration of sulphide ores.Galena $(PbS)$ is a sulphide ore.Cassiterite $(SnO_2)$ is an oxide ore.Magnetite $(Fe_3O_4)$ is an oxide ore.Malachite $(Cu(OH)_2 \cdot CuCO_3)$ is a carbonate ore.Therefore,only Galena is concentrated by the froth-flotation method,which relies on the preferential wetting of sulphide particles by oil (frothing agent) and gangue particles by water.

$I$	$II$
$X$. Magnetic separation	$a$. $Ag_2S$
$Y$. Froth floatation	$b$. $FeCr_2O_4$
$Z$. Gravity separation	$c$. $Al_2(SiO_3)_3$
