Advanced Techniques on Fine and Coarse Particle Flotation
Flotation is a method that enables the separation of hydrophobic particles with the help of air bubbles (Fig. 3 a). In flotation, the particles adhere to air bubbles depending on solid, liquid, and gas contact phases. The interaction of particles and bubbles includes collision, adhesion, and stability [ 3, 4, 5 ].
Flotation Machines
Industrial flotation machines can be divided into four classes: mechanical. pneumatic. froth separation. column. air-lift. matless. Laboratory/Test Froth Flotation Machine. As pneumatic and froth separation devices are not commonly used in industry today, no further discussion about them will be given in this module.

Flotation
On a plant of 250 tons the extra labor would bring it up to approximately 10c. per ton. Actual figures from a large plant of over 2000 tons gave 6.1c. per ton. The flotation feed in this case represents 60% of the crude-ore tonnage or 3.5c. per ton of crude ore treated. FLOTATION THEORIES
