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 longitudinally at the inner surface of the column to control the swirling of the fluid caused by the impellers.
