Question

Match the following processes with their physical principles:

• A. A-3, B-1, C-4, D-2
• B. A-2, B-4, C-3, D-1
• C. A-3, B-1, C-4, D-3
• D. A-2, B-4, C-1, D-3

Hint:

Flotation exploits surface properties (hydrophobicity), while jigging and heavy media separation depend on gravity and acceleration differences.

Answer 1

The Correct Option is D

Let us match each process with the correct principle:
- Flotation is based on differences in hydrophobicity. Hydrophobic particles attach to air bubbles and rise.
- Jigging separates particles based on differences in initial acceleration when subjected to pulsating fluid currents.
- Heavy media separation exploits the specific gravity difference, using a dense medium in which lighter and heavier particles float and sink respectively.
- Tabling relies on differential lateral movement across a sloped surface, segregating particles by size and density.
So, the correct matching is:
A-2, B-4, C-1, D-3
