WORLD LEADER IN ADVANCED FLOTATION TECHNOLOGY

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.
