Consequently, micro-nanobubbles are an important direction used to solve the flotation of fine wolframite. Safari also developed an attachment–detachment kinetic model that proves the relationship between particle and bubble size and flotation efficiency. After theoretical and experimental research, Ready and Ratcliff proposed the collision probability formula to prove that reducing the bubble size can significantly increase the collision probability. The reason for the low collision probability of ultrafine particles is mainly due to their small mass, but it can be improved to a certain extent by finer bubbles. Similarly an important parameter that affects the probability of collision is the bubble radius. As the reaction time increases, more and more particles are attached to the surface of the bubbles. The wrap angle between bubbles and particles is an intuitive manifestation of attachment and detachment. Stirring provides energy input for the flotation process, which promotes the collision of bubbles and particles. Mechanical effects also affect the collision process, such as stirring. The main mechanism of collision is interception, and a fine particle size will lead to low collision efficiency, which is not conducive to the contact between mineral particles and air bubbles. Since the middle particles as carriers are reduced, the collision and adhesion between the fine particles and the bubbles are decreased, making it difficult for the fine particles to float. Wolframite flotation has a high recovery performance for particle sizes of 10–100 μm, while the flotation efficiency of particles below this range drops sharply.
