Abstract A device for suspending solid particles in a turbulent fluid for the purpose of concentrating particles of interest such as mineral particles comprises an upright column provided with a plurality of impellers spaced along a rotatable shaft extending centrally within the column. An inlet is provided near the bottom of the column to introduce compressed gas which is dispersed by the rotating impellers to create a rising column of bubbles through a slurry of particles in a liquid so that a gas to liquid gradient is provided along the column. Disks are spaced along the shaft between the impellers, and baffles are provided longitudi- nally at the inner surface of the column to control the swirling of the fluid caused by the impellers.
