The technology behind the Column Flotation Cell. The design elements of column flotation make it unique among flotation techniques. Considerations include froth washing effects, froth recovery, residence time, cross-sectional area requirements, aspect ratio and column sparging.

Bubble surface area flux.The collection of mineral particles by bubbles greatly depends on the amount of bubble surface available. Therefore, a more adequate way of tracking the influence of gas to the flotation process is to use the amount of bubble surface per unit time and unit of column cross sectional area instead of the gas hold-up. This …
