6-8-2010 · 2.4.4 Flotation. Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015). In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.

Column and Contact Cell Flotation | Mining | SGS

Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective flotation reagents. However, in column flotation, there is no ...
