Abstract

An injector is provided in each flotation cell via which the suspension is supplied in the vicinity of the base of each flotation cell. An upwards flow of the suspension occurs, during which flotation of the dirt particles takes place. In the vicinity of the base of each flotation cell some of the suspension is drawn off and is supplied again in the circuit to the injector of the flotation cell concerned. In this way the minimum average period of dwell for all the particles of each flotation cell is correspondingly longer and the overall flotation effect is correspondingly improved.
