  • Patent number: 5251764
    Abstract: The invention relates to a flotation machine for flotating minerals from slurries containing these particles, the said flotation machine comprising a flotation cell and a mixer mechanism provided in the cell, an element for introducing air into the cell and an element for feeding the material to be flotated into the cell and for removing it therefrom. According to the invention, in the slurry chamber (2, 18) of the flotation machine, essentially below the foam bed (4, 21) created in the flotation machine, there is arranged at least one guide member (3, 19, 32), so that the free area of the flotation machine, essentially at least in the slurry chamber (2, 18) below the foam bed (4, 21) can be reduced when proceeding upwards.

  • Patent number: 5039400
    Abstract: The invention relates to a flotation machine for flotating minerals and the like from slurries containing these particles. In the flotation machine of the invention, above the feed opening (15) of the flotation cell there is formed a froth bed (11) which is adjustable in volume and/or surface area. The regulating and washing members (10, 13) of the froth bed are arranged within the froth bed (11), and the height of the froth bed is 20-40%, advantageously 30-35% of the height of the flotation cell (1).

  • Patent number: 4624777
    Abstract: The invention relates to a flotation machine designed for floating minerals from sludges containing coarse particles. The flotation machine comprises a rotor (3) and a stator (2) provided with actuator machinery and auxiliary equipment (7, 8, 9). The bottom (14) of the stator (2) is solid and the stator-rotor mechanism is located within the cell apart from the cell bottom (10). The feed inlet pipe (12) is connected to the cell so that the feed is directed towards the mixing zone of the rotor flow.
