Flotation - definition of flotation by The Free Dictionary

3. (Metallurgy) Also called: froth flotation a process to concentrate the valuable ore in low-grade ores. The ore is ground to a powder, mixed with water containing surface-active chemicals, and vigorously aerated. The bubbles formed trap the required ore fragments and carry them to the surface froth, which is then skimmed off

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.

Froth flotation financial definition of Froth flotation

While the buoyancy analysis has been greatly simplified for the sake of brevity, it should be apparent that the intentional elimination of a distinct froth phase of discernable depth and the creation of a fluidized bed of solids make it possible for the HydroFloat technology to recover much larger particles than traditional froth flotation machines.

1 Froth Flotation – Fundamental Principles

1 Froth Flotation – Fundamental Principles 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 …

differences - Is it "flotation" or "floatation"? - English ...

Some results for floatation and flotation with various related_terms are below. M = millions of hits. k = 1000's of hits. e.g. "Australia 420 k / 10.9 M" = 420,000 hits for floatation and Australia, 2.29 million hits for Australia and flotation. Very obviously this method has methodological deficiencies, but it is also demonstrably useful.

Froth flotation | ore dressing | Britannica.com

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.

60 Centuries of Copper: The Flotation Process

In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.

Flotation | ore dressing | Britannica.com

Flotation: Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.

What is the role of depressant in froth floatation process?

In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.

I think "flotation" should remain a separate keyword and not integrated into "froth flotation". In the paper industry, flotation is the key process in the recycling process for recovered paper, the deinking process. Nobody uses the term "froth flotation". I might find the time to suggest updates for both the keywords flotation and deinking.
