  • Determination of Optimum Parameters for Flotation of .

    Jan 31, 2019 · In the flotation process, air bubbles are primarily responsible for carrying the hydrophobic mineral particles to froth zone and then transferring them over the flotation cell lip. A higher number of air bubbles in the flotation cell increases the encounter/collision probability of particles with air bubbles, which increases with increasing AFR.
