[0038] The probe of the gas generator 6 adopts a special stainless steel mesh 16, so that the bubbles are further broken and the size is reduced when passing through the mesh, and the stability of the bubbles is increased.

[0039] Further, the ultrasonic cavitation assembly comprises an ultrasonic probe 4, which is arranged on the inner side wall of the flotation pipe 1, and the ultrasonic probe 4 is electrically connected with an ultrasonic power supply 5.

[0040] Further, the ultrasonic power supply 5 is provided with a display screen 12, a knob 13 and a switch 14.

[0041] Further, the flotation pipe 1 is provided with a bubble scraping inclined plate 3 at the top of the outer side wall, and a tailing discharge port 2 is arranged at the bottom of the side wall of the flotation pipe 1.

[0042] The bottom of the flotation tube 1 is sealed by the microporous air-permeable ceramic 10 as a partition, the magnetic pole six-blade rotor 11 is arranged in the sealed box, the magnetic pole 9 at the lower end of the magnetic pole six-blade rotor 11 is tightly attached to the base 15, and the magnetic force stirrer 8 at the lower part of the base 15 is opposite to the magnetic pole 9, the gas generator 6 is arranged on both sides of the microporous air-permeable ceramic 10 partition and is connected with the air pump 7 through the micropore, the ultrasonic probe 4 is arranged at the middle and lower part of the left side of the flotation tube 1, and the ultrasonic probe 4 is connected with the ultrasonic power supply 5 through the micropore of the tube wall.

The farther the air bubbles are from the blades, the smaller the air bubbles are. However, the generated air bubbles are large in size and are not suitable for micro-fine particle ore flotation. The device generates a large amount of micro-nano air bubbles by ultrasonic cavitation, increases the collision probability of the micro-fine ore, improves the adhesion effect between the particles and the air bubbles, improves the micro-fine ore flotation effect, and solves the problem that the traditional flotation cannot effectively treat the micro-fine ore.
