Abstract

The invention relates to a method for adjusting the foam surface height in a flotation cell. The invention is particularly well suited to flotation cells provided with a rotor-stator system, and especially to systems with several successive flotation cells and lines. The foam surface height (2) is regulated by adjusting the height of the chutes (5) or of the edge plates (9) of the chutes.
