Question

Match List-I with List-II : (Both having metallurgical terms)

List-I	List-II
(a) Concentration of Ag ore	(i) Reverberatory furnace
(b) Blast furnace	(ii) Pig iron
(c) Blister copper	(iii) Leaching with dilute $NaCN$ solution
(d) Froth floatation method	(iv) Sulfide ores

Choose the correct answer from the options given below :

• A. $\left(a\right)-\left(iii\right),\left(b\right)-\left(ii\right),\left(c\right)-\left(i\right),\left(d\right)-\left(iv\right)$
• B. $\left(a\right)-\left(iii\right),\left(b\right)-\left(iv\right),\left(c\right)-\left(i\right),\left(d\right)-\left(ii\right)$
• C. $\left(a\right)-\left(iv\right),\left(b\right)-\left(i\right),\left(c\right)-\left(iii\right),\left(d\right)-\left(ii\right)$
• D. $\left(a\right)-\left(iv\right),\left(b\right)-\left(iii\right),\left(c\right)-\left(ii\right),\left(d\right)-\left(i\right)$

Answer 1

The correct option is A $\left(a\right)-\left(iii\right),\left(b\right)-\left(ii\right),\left(c\right)-\left(i\right),\left(d\right)-\left(iv\right)$

Concentration of Ag are	Leaching with dil. $NaCN$ solution
Blast furnace	Pig iron
Blister copper	Reverberatory furnace
Froth floatation method	Sulphide ores

$\therefore$ Correct match is
(a) - (iii), (b) - (ii), (c) - (i), (d) - (iv)
