Design Retention time is usually obtained from laboratory testwork and proper use of Lab-to-Plant flotation scale-up …
In conventional flotation cells a certain amount of energy is required to meet the basic requirements for flotation (air dispersion, solids suspension and particle-bubble collision). This paper investigates how that energy is dissipated in the flotation cell to determine the most efficient use of the imparted energy.

CellStation uses Outotec's ExactLevel controller, which improves the metallurgical performance of flotation cells by enabling more accurate level control and significantly reducing process disturbance.
However, controlling pulp levels in flotation cells is a complex control task because of strong interactions between the levels in flotation cells. Therefore advanced controllers are needed to give good level control. This paper deals with a model of six flotation cells in series. Simulations are performed to compare different control strategies.
