Smaller droplets of oil around <10 µm may not float upwards because of Brownian motion. 7.3.1.4. Oil droplet–bubble attachment.

Principles of Air Flotation Technology SpringerLink
The process of flotation consists of four basic steps (9, 10): 1. Bubble generation in the wastewater. 2. DAF, chemicals are added to flocculate the oil and SS so bubbles can attach to and/or become entrapped in the floc to float it to the surface. In induced air flotation, chemicals are added to cause the oil and SS to engulf the airFlotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.Froth Flotation Process Detailed Explanation with Diagrams

Froth Flotation of Chalcopyrite/Pyrite Ore: A Critical Review
Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp Entrainment of Gangue Minerals in Froth Flotation Springer

Flotation process is one of the most important process factors, which has great influence on beneficiating index. The flotation process must adapt to the nature of the treated materials, and different processes should be adopted for different materials. Reasonable process flow should ensure the best beneficiating index and the lowest Ion flotation was shown to simultaneously float both molybdenum and arsenic anions (in contrast to adsorbing colloid flotation, which was able to separate Mo(VI) from other co-existing anions) .

Nanobubble column flotation of fine coal particles and
Froth flotation is a widely used, cost effective particle separation process. However, its high performance is limited to a narrow particle size range between approximately 50 to 600 μm for coal and 10 to 100 μm for minerals.Outside this range, the efficiency of froth flotation decreases significantly, especially for difficult-to-float particles As time passes in a flotation process, the bubble size becomes larger due to reducing the reagent concentration in the slurry and dropping the solid content in the cell (Hassanzadeh et al., 2017).
