Minerals | Free Full-Text | A Review on Froth Washing in Flotation
In the attempt to process lower-grade ores, mineral flotation has taken centre stage as the preferred recovery route. However, in many instances, the froth product does not have a high grade due to the entrainment of gangue minerals. Industry has solved this challenge by introducing froth washing mechanisms. Clean wash water is introduced into or on top of the …

Improving flotation energy efficiency by optimizing cell hydrodynamics
The installed power per cell (i.e. power draw) increases almost linearly with increase in cell volume (Fig. 1).On the other hand, the specific power (kW/m 3) decreases dramatically as cell volume increases from 0.02 m 3 to about 20 m 3 reaching a minimum of around 1 kW/m 3 for cell volumes greater than 100 m 3..
