In a froth flotation method and apparatus, a thick slurry is formed from a coarse-grained material and flotation chemicals. The slurry is prepared substantially without producing sludge in the slurry. In a flotation separator (2), a liquid phase is provided and a froth phase is arranged on the surface of the liquid phase. The slurry is fed into the froth phase, with the result that hydrophobic particles are caught in the froth, to be removed as a froth overflow, while hydrophilic particles sink through the froth into the liquid phase below it, to be removed as an underflow. In the preparator (1), the slurry is brought into a flowing motion with an axial vertically circulating flow pattern. The preparator (1) used is a helical rotor mixer.
