The froth flotation technique exhibits many superior features over competing technologies in recycling valuable components and constituents from spent lithiumion batteries. First, froth flotation is a physiochemical separation process that effectively preserves functional integrity of electrode materials during the recycling process .

Flotation Machine an overview | ScienceDirect Topics

Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.

Flotation an overview | ScienceDirect Topics

Flotation is widely used to separate valuable minerals from the rock and fine coal particles from clay, silt, shale, and other ashproducing matter. It is usually preceded by crushing and finely grinding the ore to liberate valuable particles in a host rock, and may be followed by metallurgical processes.

Introduction to Mineral Processing

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

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.
