Froth flotation efficiency is determined by a series of probabilities: those of particle–bubble contact, particle–bubble attachment, transport between the pulp and

Flotation Froth an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

Coal Flotation an overview ScienceDirect Topics

The froth-flotation process is used for selectively separating hydrophobic from hydrophilic minerals in a water suspension. The surface of the graphitic carbon particles is water-resistant, and thus it is very amenable to flotation in water by means of selective conditioning reagents [94–97] .

FROTHER AND COLLECTOR EFFECTS ON FLOTATION CELL

persistent, voluminous froth causes grade to drop and there are operational problems with frothing downstream. The frother may be too strong for this circuit. It is important to find the frother with the appropriate strength that will provide the optimum control in each flotation circuit across a useful range of dosages and ore conditions.

The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which

TECHNICAL NOTES 9 FLOTATION Mineral Tech

The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of a more or less stable froth. The bubbles do not burst when they cross the interface and each one carries a skin of water into the froth phase.

Dec 01, 2010 1. Introduction. The poor flotation recoveries of fine (“F” 40–13 μm) and ultrafines (“UF” < 13 μm) mineral particles is very well known and many studies, projects and processes have been proposed, but this major technical and economic problem still continues (Collins and Read, 1971, Fuerstenau et al., 1979, Trahar, 1981, Sivamohan, 1990, Song and Lu, 2000, Rubio et al., 2003
