Flotation Reagent - an overview ScienceDirect Topics

Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).

1 Froth Flotation – Fundamental Principles

2009-8-27  1 Froth Flotation – Fundamental Principles ... Particles can either be naturally hydrophobic, or the hydrophobicity can be induced by chemical treatments. Naturally hydrophobic materials include hydrocarbons, and non-polar solids such as elemental sulfur. Coal is a good example of a material that is typically naturally hydrophobic,

Flotation Froth - an overview ScienceDirect Topics

The reaction products of galvanic interaction may influence the flotation efficiency of composite minerals by direct depression or activation of minerals, or by affecting flotation froth characteristics. These reaction products, as will be shown, are not unique to galvanic processes, but their rate of formation may be enhanced by such interactions.
