Flotation columns getting the most from fine ores
In direct flotation, this froth corresponds to the concentrate. Hydrophilic particles flow down and leave the column through a barometric leg, which includes a level control system. This corresponds to the underflow and, in the case of direct flotation, to the tailings. Figure 2 illustrates the flotation process within a column.

Effect of grinding media on surface property and flotation …
Grinding reduces particle size and enables the liberation of valuable minerals from gangue minerals. During grinding, the particle size distribution, shape, and surface …
Flotation Plant Design and Production Planning …
Additionally, the flotation plant residence time will often be determined solely by the grinding circuit capacity and feed slurry density. In the case of SAG mill – ball mill circuits, the fluctuations in tonnage and grind are known to be high. The modelling approach described in this paper allows for changes in the measured flotation
Froth Flotation Process
"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories …
Recycling process water in sulfide flotation, Part B: Effect of H
