Fig. 10b shows that the recovery of composite particles with complex locking texture in the Denver flotation cell is far lower than the recovery in the fluidised-bed separator across all size fractions. The highest recovery value for the 425–600 lm fraction that could be obtained with the Denver flotation cell was approximately 16%.

Effect of feed concentration on coal flotation performance. The air flow was approximately 0 cm/s to 1.85 cm/s, shaft speed was 1800 r/min, collector dosage was 320 g/t, and frother dosage was 110 g/t. Combustible matter recovery increased to the maximum and then gradually decreased with increasing air flow rate.

A mineral processing pilot plant, owned by a Portuguese mining company, was adapted for this purpose. The experimentation showed that it is possible to produce an almost pure concentrate of PET, containing 83% of the PET in feed, in a single bank of mechanical flotation cells. The concentrate grade attained was 97.2% PET, 1.1% PVC and 1.1% PS.

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 ].

Air flotation, in all its variations, is an efficient way to extract oil from wastewater. If the wastewater is chemically pretreated to break the oil emulsions, air flotation units are capable of removing most of the emulsified oil in addition to the free oil. This chapter covers various flotation techniques to achieve oil/water separation.
