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.
