Ore concentration by froth floatation utilises the ______________ of ore particles ?
Correct answer: B. Wetting characteristics
- A. Density difference
- B. Wetting characteristics
- C. Terminal velocities
- D. None of these
Explanation
Froth flotation separates particles according to their different surface wettabilities: hydrophobic particles attach to air bubbles and rise with the froth. Density difference is the basis of gravity separation, not flotation.
