摘要： A flotation cell (1) for treating particles suspended in slurry and for separating the slurry into an underflow (400) and an overflow (500) is disclosed. The flotation cell comprises a flotation tank (10) with a centre (11), a perimeter (12), a bottom (13), and a side wall (14); and a launder (2) and a launder lip (21) surrounding the perimeter (12) of the flotation tank. The flotation tank further comprises blast tubes (4) for introducing slurry infeed (100) into the tank, a blast tube comprising an inlet nozzle (41), an inlet (42) for pressurized gas, an elongated chamber (40) and an outlet nozzle (43). The outlet nozzle is positioned at a vertical distance (L5) from the launder lip, the distance (L5) being at least 1,5 m. In addition, a flotation line and use of the flotation line are disclosed.

摘要： 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.

The flotation cell comprises a flotation tank (10) with a centre (11), a perimeter (12), a substantially horizontal level bottom (13), and a side wall (14); a launder (2) and a launder lip (21) surrounding the perimeter (12) of the tank (11); and a bottom structure (7) arranged on the bottom (13), and having a shape that allows particles suspended in slurry to be mixed in a mixing zone (A) over the bottom structure, and to settle down in a settling zone (B) surrounding the bottom structure. The flotation tank further comprises blast tubes (4) for introducing slurry infeed (100) into the tank. In addition, a flotation line and use of the flotation line are disclosed.

摘要： The invention relates to a method for constructing a flotation apparatus (1), to flotation apparatus (1), to a system for flotation, and to a connection arrangement (10) for use in the method or in the flotation apparatus (1). The flotation apparatus comprises a flotation vessel (2) and a cover (3) for closing an upwards open opening (4) of the flotation vessel (2), wherein the cover (3) and the flotation vessel (2) limits a vessel space (5) for receiving fluid, and an agitating means (6) having a rotatable axis extending through a first aperture (8) in the cover (3). The rotatable shaft (7) is rotatable supported at a bearing housing (9) outside the vessel space (5). A connection arrangement (10) surrounds the rotatable shaft (7) between the bearing housing (9) and the cover (3).
