Lesson 14: Sedimentation and Flotation
Froth flotation is commonly used in the processing of mineral ores. Modern DAF units using parallel plate technology are quite compact. The feed water to the DAF float tank is often, but not always, dosed with a coagulant, such as ferric chloride or aluminum sulfate, to flocculate the suspended matter.

Froth flotation design and operation are complex tasks because various important parameters are interconnected. The parameters can be classified into four types of components, as shown in Fig. 1 If any of these factors is changed, other parts of the design will also be changed. It is impossible to study all of the parameters at the same time.

Coal Flotation
Piloting tests showed an increase in flotation yield at a 50% reduction in diesel fuel (collector) dosage by a combination of mechanical cells and a cavitation unit (Hart et al., 2002). Further pilot testing revealed that cavitation enhanced the collection of ultrafine coal particles, while the ash content was almost the same ( Hart et al., 2005 ).
