  • Froth flotation - Wikipedia

    2020-7-14  Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

  • 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 - Simple English Wikipedia, the free

    2020-6-22  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 ...
