Evenly entering the inner cavity through several through holes can overcome the uneven contact between the ore and the air caused by the traditional instrument only having one end of air intake, thus making the ore dressing work of the device more thorough.

(2) When the utility model is in use, the foaming agent has surface active molecules of hydrophilic groups and hydrophobic groups, which can be adsorbed on the water-air interface in a directional manner, reduce the surface tension of the aqueous solution, and make the air filled in the water easy to disperse into Bubbles and generate stable foam. The foaming agent and the collector have a combined effect, and they are adsorbed on the surface of the mineral particles to promote the floating of the mineral. On the surface of the ore, the ore floats on the upper end of the buoyancy box, and then the motor provides power to drive the impeller to rotate, so that the floating ore flows from the holding groove on the side of the buoyancy box into the collection tank, and then passes through the collection tank. The through hole opened at the bottom enters the ore collection box, and the increase of the impeller can effectively improve the working efficiency of the ore dressing.
