Question
Oil that is used in the froth floatation process as a frothing agent:
- Pine oil
- Mustard oil
- Palm oil
- Coconut oil
Hint:
concentration of ore
The correct answer is: Pine oil
Oil that is used in the froth floatation process as a frothing agent: Pine oil, Pine oil is hydrophobic. The particles of the metal sulphide ores which are hydrophobic get wetted by pine oil. They float with the foam on the surface of water.
