2017-2-1 · In this process, air is dissolved into water at high pressure in a saturator, and microbubbles are formed by cavitation when water is released into the flotation tank at atmospheric pressure. These microbubbles become attached to the particles, increasing their buoyancy and allowing them to rise to the surface (Al-Shamrani et al., 2002).
