Flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals the function of the rotorstator is to make bubbles from the forced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise
