1 Froth Flotation Fundamental Principles

The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water repellent (hydrophobic). If a mixture of hydrophobic and hydrophilic particles are suspended in water,

WATER CLARIFICATION BY FLOTATION 1

Flotation is a well developed technology and publications in this field number hundreds per year. Much of this published work relates to mineral separation, the flotation techniques of which are not generally applicable to water treatment. No attempt has been made therefore to survey this in great detail; in any case it has been the subject

Flotation Froth an overview ScienceDirect Topics

Basically, particles are either hydrophilic or hydrophobic (Gutierrez Rodriguez et al., 1984). Surface properties of particles are modified with a surfactant (collector). Bubbles, produced by mechanical (froth flotation) or passive (column flotation) aeration and stabilized by a frother (a surfactant),

Froth flotation

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.

(PDF) Natural hydrophobicity and flotation of fluorite

Thus, the macroscopic contact angle of fluorite depends on the method of measurement as well as its origin and color since colorless fluorites float better. Hydrophobicity of fluorite and the time of the three phase contact formation influence its flotation.
