Flotation is a process where gas bubbles are injected at the bottom of a tank containing a mixture of a liquid and solid particles to separate the solid particles from the liquid. When the gas bubbles move along the liquid mixture, the solids particles stick to the surface of the bubbles. The bubbles form a foam at the surface of the liquid: this foam contains the solid particles, so after the

Evaluation of Frother Types for Improved Flotation
Initial froth flotation tests involved identifying the volumetric feed flow rate that resulted in a near optimum separation performance (i.e., maximum coal recovery and ash rejection). The feed flow rate was varied from 300 mL/min to 2000 mL/min at a constant feed solids concentration of 5% by weight. The optimum feed volumetric flow rate was determined to be 1000 mL/min. As such, all of the

MECHANICS OF FLOTATION The basis of Froth Flotation is the difference in the WETTABILITY of the mineral and gangue particles. On the basis of Wettability of particles are classified as HYDROPHOBIC and HYDROPHILIC. The valuable minerals can attach to the air bubbles,only if they are Hydrophobic. Once they reach the surface, due to the buoyancy of the air bubbles, the particle-bubble contact
Froth Flotation Definition of Froth Flotation by Merriam
Froth flotation definition is flotation in which air bubbles are introduced into a mixture of finely divided ore or other material with water and a chemical that aids attachment of the bubbles to the particles of the desired material and its recovery as a froth.

of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles. Within this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified. Each of these plays a role in determining how individual solid
