4.2. Column Flotation The application of column cells in the mineral processing industry has gone from virtually zero in 1983 to wide acceptance in 1990[5557]. The major operating difference between column flotation cells and mechanical flotation cells is the lack of agitation in column flotation which reduces energy and maintenance costs[58].

COLUMN FLOTATION MODELLING AND TECHNOLOGY

Finally, the existence of a single threedimensional froth in the column makes the study of the process simpler than that for a bank of mechanical cells, where the froth characteristics change from cell to cell. Industrial flotation columns are square or circular, typically 0.53m in diameter or side, and 1215m height.

FLOTATIONFroth Processes and the Design of Column

The function of a Sotation column is selectively to separate certain suspended solid particles or liquid droplets based on their surface properties. Bubbles rise and particles drops settle within the vessel, and collisions are highly dependent on gravitational momentum. The vessel is a multiphase contacting/heterocoagulation device where the dispersed phase to be removed attaches to the
