Froth floatation process of concentration is based on the
A
Preferential wetting properties with the frothing agent and water
B
Difference in the specific gravities of gangue and ore particles
C
Difference in solubility of gangue and ore particles in frothing agent and water.
D
Difference in reactivity of gangue and ore particles with water and frothing agent.
Answer
Preferential wetting properties with the frothing agent and water
Explanation
Solution
Froth floatation method is based on preferential wetting properties with the frothing agent and water. Sulphide particles of the ore stick to the oil droplets and rise to the surface in the form of froth and gangue particles are wetted by water and thus sink to the bottom.
