Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Check Statement-I.
Low boiling metals like Zn and Hg are refined by distillation. Hence Statement-I is true.
Step 2: Check Statement-II.
Copper matte obtained during extraction contains \[ Cu_2S \] and \[ FeS \] Hence Statement-II is accepted as true.
Step 3: Check Statement-III.
Froth flotation is specifically used for concentration of sulphide ores. Therefore Statement-III is true. \[ \boxed{\text{I, II and III}} \]
Low boiling metals like Zn and Hg are refined by distillation. Hence Statement-I is true.
Step 2: Check Statement-II.
Copper matte obtained during extraction contains \[ Cu_2S \] and \[ FeS \] Hence Statement-II is accepted as true.
Step 3: Check Statement-III.
Froth flotation is specifically used for concentration of sulphide ores. Therefore Statement-III is true. \[ \boxed{\text{I, II and III}} \]
