Froth Flotation Cells by Parnaby Cyclones

Froth Flotation Cells. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that ...

Froth Flotation Process

Basic Principle of Froth Flotation Process. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry.

1 Froth Flotation – Fundamental Principles

The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water-repellent (hydrophobic). If a mixture of hydrophobic and hydrophilic particles are suspended in water, and air is bubbled through the suspension, then the hydrophobic particles will tend to attach to the air bubbles and float to the surface, as shown in Figure 3. The froth …

Froth Flotation Process

Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig. 17). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles.

TECHNICAL NOTES 9 FLOTATION

The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of a more or less stable froth. The bubbles do not burst when they cross the interface and each one carries a skin of water into the froth phase.

Flotation Reagents

 · The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

Flotation Froth

Froth Drainage. The use of froth in flotation is twofold. Firstly, froth is used to convey the mineral laden bubbles from the froth-pulp interface to the concentrate launder. Secondly, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp ( Figure 13).
