摘要

A control method of a flotation machine that is used in metallurgical processes. The flotation machine foams hydrophobic particles from an aqueous slurry that contains these particles. The flotation machine includes a flotation cell (1) and a rotor (2), which is inside the flotation cell and in which the rotor is rotated at a mixing power that maintains a suspension in the slurry and mixing of air with the slurry to form foam, and the mixing power is controlled by adjusting the rotation speed of the rotor. The amount of solid matter accumulated on the bottom of the cell is determined, and the rotation speed of the rotor is continuously kept at the lowest possible standard value at which the determined amount of solid matter accumulated on the bottom of the cell will not exceed a predetermined limit value.
