Mixing and Hydrodynamics in Flotation Cells | SpringerLink
Abstract. The flotation process is a complex interaction between the physicochemical characte- ristics of the species involved and the hydrodynamic and operating conditions in flotation cells. Efficient cell design requires knowledge about the power to be provided and the time to be spent in the cell by each one of the phases.

Technological assessments on recent developments in fine …
Comparative laboratory results between oscillating grid and Denver flotation cells indicated that the OGC improved mineral floatability through relatively isotropic and homogeneous turbulence, variable energy dissipation rates (0.5–5 kW/m 3) and generation of small bubble sizes (0.13–0.83 mm). However, full-scale studies for this cell type ...
