Flotation Kinetics - an overview ScienceDirect Topics

Flotation process is based on the difference in the surface hydrophobicity of different components. In a traditional flotation cell, high speed impeller agitation is required to keep particles in suspension. Collectors such as xanthate salts related sulphur-based ligands and nonpolar oils (diesel and kerosene) are usually used to make valuable minerals hydrophobic while depressors are used sometimes to render gangue particles hydrophilic. Air is introduced or sometimes forced into the cell ...Flotation process is based on the difference in the surface hydrophobicity of different components.

01/06/2018  The force is obtained by multiplying the measured probe deflection by the spring constant of the cantilever. In the colloid probe technique, a micrometer-size particle is attached to the end of the cantilever and replaces the sharp tip. Usually the particle is spherical to facilitate the quantitative analysis. Thus, the interaction geometry between the probe and surface is greatly simplified.01/06/2018  The force is obtained by multiplying the measured probe deflection by the spring constant of the cantilever.

Froth zone: Zone in the top of the flotation cell consisting of froth loaded with mainly valuable minerals, which provides extra separation between valuable minerals and gangue minerals. Gangue minerals: Unwanted, barren minerals, without valuable mineral or metal content. Gas holdup: The volume fraction of a flotation cell occupied by gas.Froth zone: Zone in the top of the flotation cell consisting of froth loaded with mainly valuable minerals, which provides extra separation between valuable minerals and gangue minerals.
