separation by flotation suspension

Froth flotation ore dressing Britannica

Froth flotation, separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water. See flotation. This article was most recently revised and updated by Erik Gregersen, Senior Editor.

FLOTATION Thermopedia

Flotation is a process in Liquid Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 m.

Colloidal Titanium Dioxide Separation from Water by Foam

ABSTRACT Colloidal titanium dioxide (TiO2) was separated from an aqueous suspension (1000 ppm) by foam flotation using cationic or anionic surfactants. The effects of surfactant dosage, suspension pH value, suspension ionic strength, and gas flow rate on the dispersed air flotation of colloidal TiO2 were investigated. TiO2 separation was almost complete in optimum conditions.

Gamma Flotation 911metallurgist

Flotation is a well known surface chemistry based particulate materials separation process which utilizes differences in wettabilities of solids. The operating mechanism in the process is that finely divided particles are rendered hydrophobic by the adsorption of suitable flotation reagents, so that they are captured by the rising stream of bubbles which collide with them.
