Question

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

List-I		List-Il
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. (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
• B. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
• C. (a)-(iv), (b)-(i), (c)-(iii), (d)-(ii)
• D. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

Answer 1

Answer: (A)

(a) Concentration of $Ag$ is performed by leaching with dilute $NaCN$ solution
(b) Pig iron is formed in blast furnace
(c) Blister $Cu$ is produced in Bessemer converter
(d) Froth floatation method is used for sulphide ores.
Note : During extraction of $Cu$ reverberatory furnace is involved
