Denver Introduces New Flotation Mechanism | C&EN …
A new impeller mechanism for flotation machines is now being manufactured by Denver Equipment Co., of Denver, Colo. Denver says the mechanism, which it calls the D-R Denver flotation mechanism, betters flotation efficiency by improving aeration and by increasing the amount of recirculation in a flotation cell. As a consequence, users can …

Flotation
How the data is used to determine flotation kinetics is a subject of a separate video. The key aspects are: the types and setup of the laboratory cell; sample to be tested, test conditions and; how the test is conducted. The standard laboratory cell and cell size for many decades has been the Denver D12 with 2.5 litre stainless steel cell.

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 ...
