Correct answer: D. Step 1: The froth floatation process exploits the differential wetting behavior of sulfide ores and gangue particles. Step 2: Hydrophobic collector molecules (like potassium ethyl xanthate) selectively adhere to and accumulate on the surfaces of the sulfide ore particles. Step 3: This selective surface concentration of the collectors and air bubble attachment is a practical application of adsorption, corresponding to option (a).
