Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method where minerals can be "skimmed" from the surface of "slurry" that is "foamed" with the assistance of specific chemicals, water, and air bubbles.

flotation process

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore .Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

Kinetics of flotation

Flotation kinetics (from the Greek Kinētiks - driving) is studying the regularities of flotation process at the time, the rate and the flotation mechanism.

Mineral Processing Introduction

The flotation process begins with a modification of the surface properties of the desired mineral. The addition of surfactants renders the mineral surface hydrophobic (water-hating), so that the mineral may preferentially adhere to air bubbles and float to the surface.

The tailings can be scrubbed prior to flotation with sulfuric acid, hydrochloric acid or sodium hydroxide. The scrubbing removes coatings on the minerals which would inhibit separation of the minerals during the flotation process. It has been determined that sodium hydroxide is advantageous for removing coatings and is economically preferable.
