Q. Which of the reaction is suitable for concentrating ore by leaching process ?

$2 C u_{2} S + 3 O_{2} \to 2 C u_{2} O + 2 S O_{2}$

$F e_{3} O_{4} + CO \to 3 F e O + C O_{2}$

$A l_{2} O_{3} + 2 N a O H + 3 H_{2} O \to 2 N a [A l (O H)_{4}]$

$A l_{2} O_{3} + 6 M g \to 6 M g O + 4 A l$

$A l_{2} O_{3} + 2 N a O H + 3 H_{2} O \to 2 N a, [A l (O H)_{4}]$ Leaching.
