The flotation machine is an important equipment for realizing the flotation process. At present, when the flotation machine is used for flotation, the ore pulp is sent into the flotation machine after being mixed with the flotation reagent, and the desired floating mineral is attached to the gas bubble to form a mineralized bubble, which is floated to the surface of the ore pulp to form a mineralized bubble layer.
