There is practically no alternative/competitor to _________________ in the beneficiation treatment of sulphide ores?
Correct answer: D. Froth floatation
- A. Classification
- B. Tabling
- C. Jigging
- D. Froth floatation
Explanation
Froth flotation selectively attaches hydrophobic sulphide mineral particles to air bubbles, allowing them to be separated from gangue. Classification, tabling and jigging are less effective as general alternatives for sulphide-ore beneficiation.
