Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water. The physical and chemical interactions determine the outcome of the flotation process.

Flotation Column Cells can only 'carry' or recovery so much froth/concentrate for any given diameter. Unlike a mechanical cell on which you can just turn-on more air to recover more metal, column cells with not respond that way. A column cell can only carry so much froth to the concentrate launder. Their concentrate production is ...
