Vedclass · Answer

(B) The correct matching is as follows:$(I)$ Magnetic separation is used for magnetic ores like chromite,$FeCr_2O_4$ $(b)$.$(II)$ Froth flotation is used for sulphide ores like chalcocite,$Cu_2S$ $(a)$.$(III)$ Gravity separation (levigation) is used for ores with high density compared to gangue,such as silicate ores like $Al_2(SiO_3)_3$ $(c)$.Therefore,the correct match is $(I-b, II-a, III-c)$.

$I$ (Method)	$II$ (Ore)
$(I)$ Magnetic separation	$a. Cu_2S$
$(II)$ Froth flotation	$b. FeCr_2O_4$
$(III)$ Gravity separation	$c. Al_2(SiO_3)_3$

Match the method of concentration of ore in Column $I$ with the ore in Column $II$.

$I$ (Method) $II$ (Ore)

$(I)$ Magnetic separation $a. Cu_2S$

$(II)$ Froth flotation $b. FeCr_2O_4$

$(III)$ Gravity separation $c. Al_2(SiO_3)_3$
