Abstract

A flotation cell for treating particles suspended in slurry is disclosed. The flotation cell comprises a flotation tank (10) comprising a centre (11), a perimeter (12), and a sidewall (13); a launder (2) and a launder lip (21) surrounding the perimeter (12) of the tank (11); and a downcomer (4). Aheight- to-diameter ratio of the flotation cell is 0,9 or lower. The downcomer (4) comprises an inlet nozzle (41) for feeding slurry infeed into the downcomer; an inlet (42) for pressurized air; an elongated chamber (40) arranged to receive under pressure the slurry infeed; and an outlet nozzle (43) configured to restrict the flow of slurry infeed from the outlet nozzle, and to maintain slurry infeed in the elongated chamber under pressure.In addition, a flotation line and use of the flotation line is disclosed.
