The flotation apparatus includes a flotation vessel and a cover for closing an upwards open opening of the flotation vessel, wherein the cover and the flotation vessel limits a vessel space for receiving fluid, and an agitating means having a rotatable axis extending through a first aperture in the cover. The rotatable shaft is rotatable supported at a bearing housing outside the vessel space. A connection arrangement surrounds the rotatable shaft between the bearing housing and the cover.

Method for constructing a flotation apparatus, flotation apparatus, method and system for flotation and use

An air distribution and mixing device is arranged in the vicinity of the bottom of a flotation cell for distributing air to the slurry for forming froth and mixing the slurry in the flotation cell. A rotor part of the air distribution and mixing device has air distribution apertures and is attached to the lower end of a drive shaft extending vertically in the flotation cell. The drive shaft has a hollow interior, which constitutes a flow channel for conducting flotation air to the air distribution holes of the rotor part. An electric motor for rotating the drive shaft is supported by a separate supporting framework, which is on top of the flotation cell. The electric motor is a permanent magnet motor having a vertical rotor shaft, the lower end of which is in permanent contact directly with the upper end of the drive shaft.
