Basic Idea Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter-current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell. The sparger technology is an important design choice, and allows the user to optimize the performance based on the feed …

Flotation machines and flotation columns are widely used as separation equipment for coal sludge. In order to obtain better flotation results for different particle sizes, the bubble distribution and size in the flow field need to be studied. In this paper, a novel three-phase fluidized bed flotation column (TFC) was designed, and the shear effect of liquid velocity (0.198 …

Flotation is a separation process based on differences in surface physicochemical properties to achieve the high-efficient recovery of valuable minerals from lower ore grades [1], [2], with the optimal particle size typically ranging from approximately 10 to 150 μm [3], [4], [5].Beyond this size range, flotation recovery decreases significantly, especially for coarser particles [6], [7].
