column flotation cell design

the introduction of column flotation. Flotation columns differ radically from conventional mechanical flotation units both in design and operating philosophy. This has been a cause of the reluctance to test these units industrially since their invention (in Canada) in the mid-60's by Boutin and Tremblay.
