- A-I, B-II, C-III, D-IV
- A-II, B-I, C-IV, D-III
- A-IV, B-III, C-II, D-I
- A-III, B-II, C-I, D-IV
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
In mineral processing:
- Concentrate → valuable mineral-rich fraction
- Tailings → waste material discarded
- Middlings → intermediate partially liberated material
- Gangue → unwanted non-valuable material
Step 1: Concentrate.
High-grade ore fraction: \[ A \rightarrow I \]
Step 2: Tailings.
Rejected waste: \[ B \rightarrow II \]
Step 3: Middlings.
Intermediate material: \[ C \rightarrow III \]
Step 4: Gangue.
Unwanted impurities: \[ D \rightarrow IV \] Final Answer: \[ \boxed{A-I,\; B-II,\; C-III,\; D-IV} \]
