results and mechanism, the following conclusions can be
summarized:
(1) Under pH 11, α-BLA dosage of 200 mg/L, starch
dosage of 10 mg/L, and Ca2+ concentration of 150 mg/L,
introducing micro-nano bubbles can increase the flotation
difference between chlorite and hematite. Under the same
conditions, the flotation difference increased by 13.69%.
When micro-nanobubbles are introduced, and the dosage
of α-BLA is reduced by 50 mg/L, the recovery of chlorite
can still be increased by more than 6%.
(2) The synergistic effect of starch, Ca2+, and α-BLA
effectively adjusts the surface properties of minerals.
Furthermore, introducing micro-nano bubbles improves
the theoretical flotation recovery and flotation speed con-
stant of chlorite. The existence of micro-nano bubbles can
reduce the interaction energy barrier between particles and
conventional bubbles through long-range hydrophobic
force, which is also one of the essential reasons for improv-
ing its flotation speed.
