FROTH FLOTATION involves three different phases- solid fine ore powder, liquid water and froth. The process of separation of mineral includes three important mechanisms 1. TRUE FLOTATION, i.e., selective attachment to air bubbles. 2. ENTRAINMENT in the water which passes through the froth. 3.
To work efficiently, flotation cells depend on continuous froth formation. If the froth layer is too thin, it cannot transport the sufficient amount of dispersed or suspended particles to the surface. On the other hand, froth that is too thick indicates that the reaction time of the chemicals is too long.
Flotation process sometimes called flotation separation is a method of separation widely used in the wastewater treatment and mineral processing industries. fPRINCIPLES OF FLOTATION. Mechanism of froth flotation are Attachment of a specific mineral particle to air bubbles Being carried by the water in the floth Caught bw particles in the froth.

Froth Flotation is one of the industrys standard ways of concentrating low grade, fine particle sized minerals. This process is done by using water as a medium and manipulating the particles surface chemistries into being either hydrophobic or hydrophilic then using air bubbles to separate the hydrophobic particles.
or less stable and mobile layer of froth will persist on the surface of the slurry which will gather and recover a proportion of the adhering mineral particles. 8.1 A Kinetic Approach to Flotation Modeling Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process.
Provision to remove froth by the use of froth paddles on all flotation cells should be included in the original design. The additional capital cost required for froth paddles is a reasonable investment since these devices tend to negate errors in flotation pulp level or frother addition.
