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 …

Flotation Cells Design & Operating Characteristics
In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).
