After conditioning, the froth height and gas flowrate were set to 1 cm and 11.5 L/min, respectively.In flotation, superficial gas velocity (J g) is the parameter usually used to represent the air flowrate as it is independent of cell size.In industrial applications, J g usually ranges from 0.5 to 3.0 cm/s (Neethling and Cilliers, 2009).In this study, a J g …

Flotation of fine particle (<37 μm) and ultrafine particle (<8–13 μm) is a key challenge. Feed in flotation consists of wide range of particle size, therefore, flotation column needs to have wider bubble size to target fine as well as coarse size particles [13,14]. So, flotation of fine particles is one of the major challenging tasks.

Neutral buoyancy occurs when the average density of an object is the same as the density of the fluid it is immersed in. When the object is below the surface, it neither sinks nor floats. It can be positioned at any depth below the surface and will stay there until another force moves it to a new location.

The surface is the contact region where many adsorptions occur during the flotation process. Unlike these of stable coordination composition in the bulk structures, the atoms of the surfaces tend to form different terminations due to the breaking of the fracture bonds [33].Therefore, the surface structure has very different atom states from the bulk, …
