A practical approach to plant-scale flotation optimization
The only way to reliably know the amount of air entering a flotation cell is to physically measure it with some kind of probe. The APBS can be used to measure J g and bubble size in an industrial flotation cell. It is impractical to physically measure J g each time an air rate is changed on a plant. However, it is possible to generate linear ...

Flotation Plant Simulation
Of these, perhaps the most interesting is the fact that, from the point of view of simulator structure, all the flotation cells in the plant are identical. This configurational simplicity is further enhanced by the fact the model equations for the performance of individual cells do not change from cell to cell. The model equations are naturally ...

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 rate constant for the …
