Improving the recovery of coarse particles (+0.150 mm) has been a long-standing goal within the minerals processing industry. The relationship between particle size and floatability was presented early in the literature based on research conducted by Gaudin et al. (1931) which showed that coarse particles are more difficult to recover than intermediate size particles.

Flotation can effectively realize the recovery of valuable minerals according to the difference in surface hydrophobicity of minerals, and its separation particle size range is usually 5–150 μm [[1], [2], [3]].In the flotation process, hydrophobic minerals can collide and attach with bubbles to form aggregation, which then gather at the air-water interface to form concentrate.
