Modelling and simulation of rougher flotation circuits
Highlights A rougher flotation simulator based on data from plant measurements is presented. Metallurgical characterisation was developed by mass balance and kinetic adjustments. The grinding effect was modeled using distributed flotation rates per size class. The simulator was calibrated using data from 130 m 3 cells in rougher …

Deister Flotaire Column Flotation Cell-Plant Experience
The Deister Flotaire Column Flotation Cell was originally designed and developed to process coarse and hard-to-float phosphate minerals, and was first commercialized in 1977. Shortly after its introduction, 15 full-size 2.4 m (8.0 ft.) dia. and numerous smaller diameter laboratory and pilot units were installed in the phosphate industry.

A novel scale-up approach for mechanical flotation cells
Gorain et al. (1997a,b) and Alexander et al. (2000) suggested the use of the bubble surface area flux as the scale-up criterion by considering a linear relationship with the flotation rate. This approach was tested for cells over 50 L, where they believe the hydrodynamic effect (turbulence) to be less significant.
