The addition of nanobubbles causes the optimal flotation pulp pH of rutile to move to a high pH. If the pH value continues to increase, the flotation recovery of rutile should also be significantly reduced, which indicates that nanobubbles only act as auxiliary collectors in the process of rutile flotation.
