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
(d) Froth floatation method	(iv) Sulfide ores

Choose the correct answer from the options given below : 

(1) (a)–(iii), (b)–(ii), (c)–(i), (d)–(iv) 

(2) (a)–(iii), (b)–(iv), (c)–(i), (d)–(ii) 

(3) (a)–(iv), (b)–(i), (c)–(iii), (d)–(ii) 

(4) (a)–(iv), (b)–(iii), (c)–(ii), (d)–(i)

Answer 1

(1) (a)–(iii), (b)–(ii), (c)–(i), (d)–(iv)

(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.
