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.

A novel scale-up approach for mechanical flotation cells
The scale-up relationship was developed based on dimensionless parameters. First, a scale-up factor (ξ) was defined as the ratio between the actual flotation rate (k AC) of the collection zone in a perfectly mixed industrial cell (N = 1) and the flotation rate (k B) in a laboratory batch cell, (1) ξ = k AC k B The apparent flotation …
