A review of froth flotation control

Froth flotation is a three phase separation process for complex ores based on the manipulation of the difference in hydrophobicity of the solids. Suspended, hydrophobic metal-rich particles are contacted with, and subsequently combine to, air bubbles — whilst the more hydrophilic gangue particles sink and are recovered to the tails stream. ...

1 Froth Flotation – Fundamental Principles

rock and to a size range suitable to be floated (10 - 200 microns). 2. Creating a rising current of air bubbles in the pulp. 3. Making conditions favourable for the desired mineral particles to adhere to air bubbles. 4. Forming a mineralized froth on the surface of the ore pulp. 5. Removing the froth from the flotation cell or vessel.

Conditions of operation of froth-flotation. Froth-flotation is in general effective only on ores ground to pass 0.3-mm. aperture or less and the agitation-froth and bubble-column processes are most effectively practiced when the bulk of the feed will pass a 0.074-mm. screen. In these latter processes the finely pulverized ore must be in the ...

Froth Flotation Technique Method Procedure

Frothers are the reagents necessary to produce the mineral- carrying froth. The quantity consumed is 1/20 to 1/5 pound per ton of ore. For sulphide flotation various wood oils have been used, the most common being pine oil, particularly steam-distilled. Cresylic acid is a common frother of another type.

Flotation Conditioning

It is not often possible, however, to allow mineral particles larger than 48 mesh to enter the flotation machines because they have too great a tendency to drop out of the froth ; only a few substances of a special nature, such as coal, graphite, and molybdenite, can be floated at a coarser mesh.

Flotation

As a rule, a pulp containing particles larger than 48 mesh (0.295 mm.) is not suitable for flotation, nor is it common for the ore to be ground to a product finer than that at which 95% will pass through a 200-mesh screen (0.074 mm.). The size of the finished material usually lies between these two limits.
