Flotation columns derive their name from the geometric shape of the vessel. Unlike conventional mechanical cells, column cells are tall vessels ranging in height from 25 feet (7.6m) to more than 50 feet (15.2m). The surface area of a column cell is smaller than that of a mechanical cell which helps to promote a stable and deep froth.

— Until the pulp level has had a chance to equalize to its pre-set level the froth column will be shallower. Once the slurry is back to its operating level the extra air that was added to the cell is taking up space, this of course will cause the speed that the pulp flows through the cell to increase lowering the effectiveness of the process.
